Create a Simulink Report Generator Report Interactively

This example shows how to use the Report Explorer to design a report setup file and generate a report that does the following:

  • Opens a Simulink® model for the van der Pol equation, called the vdp model.

  • Sets the Gain parameter for the Mu block to five different values.

  • Simulates the model each time the Gain parameter is set.

  • Collects the results. Results that fall within a specified range appear in a table in the generated report.

You do not need to know MATLAB® or Simulink software to create and run this example report. However, knowledge of these products might be helpful for understanding the MATLAB code and model simulation that executes.

To create this report, you perform these main tasks:

This example includes separate sections for different kinds of report creation and generation task. Each section builds on the previous sections. However, if you want to see the report setup components for a later section without doing the previous sections, in MATLAB you can view the completed report setup file by opening Dynamic Simulink Report. The report is for the vdp model.

Note

For another set of step-by-step examples for creating and generating a report, see the Introduction to System Design Description Reports example.

      Simulink Dynamic Report
      
      This report opens up a model, sets a block parameter 
      several times, simulates the model, and collects the
      results. Results that fall within a specified range are 
      displayed in a table after the test is complete.
      
      The report is configured to test the vdp model only.
      By selecting the Eval String component immediately 
      below the Report component, you can modify
      * model
      * block
      * parameter
      * tested values
  5. Click File > Save As to save the report setup file as simulink_tutorial.rpt.

    The Outline pane on the left displays the new file name.

To create the content for the report, see Add Report Content with Components.

Add Report Content with Components

Report Components

Report components specify what information to include in the report. Components are self-contained, modular MATLAB objects that control the report-generation process and insert elements, such as tables, lists, and figures, into a report setup file. Use components to customize the appearance and output of reports.

For more information, see Report Components.

The following figure shows a sample page from the report you create in this example, and which components you use to produce this output.

Note

Do not deactivate report components that you add to the report setup file.

Add MATLAB Code

Note

This section builds on the previous tasks described in the step-by-step example summarized in Create a Simulink Report Generator Report Interactively.

To see the completed report setup file, open Simulink Dynamic Report. The report is for the vdp model.

The first component to add is the Evaluate MATLAB Expression component, which evaluates MATLAB commands in the workspace. The code in this component assigns initial values to variables used in this example.

  1. In the Outline pane on the left, select simulink_tutorial.rpt.

  2. In the Library pane in the middle, under the MATLAB category, select Evaluate MATLAB Expression.

  3. In the Properties pane on the right, click the icon next to Add component to current report to insert the component into the report.

    Note

    You cannot edit the component information in the Properties pane on the right until you add the component to the report.

    In the Outline pane on the left, the Evaluate MATLAB Expression component appears under the simulink_tutorial report setup file. The Simulink Report Generator™ software abbreviates the component name to Eval.

    The icon in the upper-left corner of the Eval component's icon indicates that this component cannot have child components. By default, any components you add while the Eval component is selected are siblings of this component.

    The options for the Evaluate MATLAB Expression component appear in the Properties pane on the right.

  4. Clear the Insert MATLAB expression in report and the Display command window output in report check boxes so you do not include MATLAB code or output in this report.

  5. Add MATLAB code to the Expression to evaluate in the base workspace text box to specify the following values:

    • The model name

    • The block name

    • The block parameter

    • Parameter values

    • Other initial values required for processing the vdp model

    Replace the existing text with the following MATLAB code.

    %The name of the model
    %that will be changed
    expModel='vdp';
    
    %The name of the block in the model
    %that will be changed
    expBlock='vdp/Mu';
    
    %The name of the block parameter
    %that will be changed
    expParam='Gain';
    
    %The values that will be set
    %during experimentation
    expValue=[-1 0 .5 1 2];
    
    %expValue can be either a vector
    %or a cell array
    
    testMin=2.1;
    testMax=3;
    
    %---- do not change code below line ---
    
    try
       open_system(expModel);
    end
    
    expOkValues=cell(0,2);

    Note

    When you change a field in the Properties pane on the right, the field background changes color (the default is a cream color), indicating that there are unapplied changes to that field. As soon as you perform operations on another component, the Simulink Report Generator software applies the changes, and the background color becomes white again.

  6. Select the Evaluate this expression if there is an error check box.

  7. In the field under the check box, replace the existing text with the following text:

    disp(['Error during eval: ', evalException.message])
    The Report Explorer window now looks as follows.

    Tip

    To run the commands that you specified in your MATLAB expression, click the Eval Now button. This button is located at the upper-right corner of the Report Explorer. This is an easy way to ensure that your commands are correct and will not cause report generation problems.

  8. Click File > Save to save the report setup file.

For information about handling error conditions, see Error Handling for MATLAB Code (MATLAB Report Generator).

Add a Title Page

Note

This section builds on the previous tasks described in the step-by-step example summarized in Create a Simulink Report Generator Report Interactively.

To see the completed report setup file, open Simulink Dynamic Report. The report is for the vdp model.

Create a custom title page for your report using the Title Page component.

  1. In the Outline pane on the left, select the Eval component.

  2. In the Library pane in the middle, under the Formatting category, click Title Page.

  3. Click the icon next to Add component to current report.

    The Title Page component appears in the Outline pane.

    Note

    To use the Title Page component, you need to have a Chapter component in your report . You have not yet added a Chapter component, so the Properties pane displays a message indicating that chapters are required for the Title Page component to appear correctly. Because later in this example you add Chapter components to this report, you can ignore that message.

  4. In the Properties pane on the right:

    1. In the Title text box, enter:

      Dynamic Simulink Report
    2. In the Subtitle text box, enter:

      Using Simulink Report Generator to Document Changes
    3. In the Options section, choose Custom Author from the selection list.

    4. Enter your name in the text box.

    5. Select the Include report creation date check box.

    6. Select the default date and time format from the selection list. The Properties pane on the right looks as follows.

Open the Simulink Model

Note

This section builds on the previous tasks described in the step-by-step example summarized in Create a Simulink Report Generator Report Interactively.

To see the completed report setup file, open Simulink Dynamic Report. The report is for the vdp model.

The following statement in the Evaluate MATLAB Expression component that you created in Add MATLAB Code tries to open the vdp model:

try
   open_system(expModel);
end

Tip

Select the Eval component in the Outline pane on the left to look at this code again.

To see if the vdp model was successfully opened, test the result of the open_system command using a Logical If component.

  1. In the Outline pane on the left, select the Title Page component.

  2. In the Library pane in the middle, under the Logical and Flow Control category, select Logical If. This component checks to see if a given condition is true or false; in this case, if the model opened successfully.

  3. In the Properties pane on the right, click the icon next to Add component to current report. The Logical If component appears as if in the Outline pane.

    These components are child components of the report and siblings of one another. Components can have parent, child, and sibling relationships.

    This component can have child components. Add Logical Then and Logical Else Components explains how to add two child components to the if component.

  4. In the Properties pane on the right, in the Test expression text box, replace the default text, true, with the following text:

    strcmp(bdroot(gcs),expModel)
    The strcmp function compares the name of the open Simulink model and the value of expModel, which was set to 'vdp'. It tests to see if the vdp model opened successfully. strcmp returns 1 (true) if the two strings match, and 0 (false) if not.

  5. Save the report setup file.

    The if component name in the Outline pane changes to include the expression that you added.

Add Logical Then and Logical Else Components

    2. Enter Post-Test Analysis in the text box.

  4. In the Outline pane on the left, select the new Section 1 component.

  5. In the Library pane in the middle, under the Formatting category, double-click Paragraph. Do not change its properties.

  6. To check whether there are any signal values within the desired range, check the array expOkValues with a Logical If component. If expOkValues is empty, there are no signal values in the desired range. Report the result of this check.

    1. In the Outline pane on the left, select the Paragraph component and add a Logical If child component.

    2. In the Properties pane on the right, enter the expression to evaluate in the Test expression text box:

      ~isempty(expOkValues)
      This expression evaluates to 0 (false) if expOkValues is empty; otherwise, it evaluates to 1 (true).

    3. In the Outline pane on the left, select the if (~isempty(expOkValue)) component and add the Logical Else component as a child.

    4. Select the if(~isempty(expOkValue)) component again and add the Logical Then component as a child.

      The two components are siblings in the Outline pane on the left.

  7. Save the report setup file.

  8. Now, insert report components to handle the case where expOkValues is empty; that is, where no signal values fall within the designated range.

    1. In the Outline pane on the left, select the else component.

    2. In the Library pane in the middle, double-click the Text component to add it as a child of the else component.

    3. In the Properties pane on the right, in the Text to include in report text box, enter the following:

      None of the selected iteration values had 
      a maximum signal value between %<testMin> and %<testMax>.

  9. Now handle the case where expOkValues is not empty and you want to insert a table of the acceptable signal values.

    1. In the Outline pane on the left, select the then component.

    2. Add a Text component as a child to the then component.

    3. In the Properties pane on the right, in the Text to include in report text box, enter the following text.

      %<size(expOkValues, 1)> values for %<expBlock> were 
      found that resulted in a maximum signal value greater
      than %<testMin> but less than %<testMax>. The following
      table shows those values and their resulting signal maximum.

    4. In the Outline pane on the left, select the Text component under the then component of the if (~isempty(expOkValues)) component.

  10. To create an array for use when formatting the table, use the Evaluate MATLAB Expression component.

    1. In the Library pane in the middle, double-click Evaluate MATLAB Expression.

    2. In the Properties pane on the right:

      1. Clear the Insert MATLAB expression in report and Display command window output in report check boxes.

      2. The next component of the report uses the strings Mu Value and Signal Maximum as table header values. Add the strings to the front of the expOkValues cell array by entering the following text into the Expression to evaluate in the base workspace text box:

        expOkValues=[{'Mu Value','Signal Maximum'} expOkValues];

      3. Make sure you select the Evaluate this expression if there is an error check box. Enter the following text into the text box:

        disp(['Error during eval: ', evalExpression.message])

  11. In the Outline pane on the left, select the Eval component.

  12. In the Library pane in the middle, under the Formatting category, double-click the Table component so it becomes a sibling of the Text and Eval components.

  13. In the Properties pane on the right:

    1. In the Workspace variable name text box, enter expOkValues. The Simulink Report Generator software uses the contents of expOkValues to construct the table.

    2. In the Table title text box, enter Valid Iteration Values.

  14. Save the report setup file.

    The Outline pane on the left looks as follows.

Generate the Report

To generate the report, click the Report icon on the toolbar. The following occurs:

  1. A Message List window appears, displaying informational and error messages as the report is processed. Specify the level of detail you would like the Message List window to display while the report is being generated. Options range from 0 (least detail) to 6 (most detail). Click the selection list located under the title bar of the Message List window to choose an option.

    Message level 3 (Important messages) is used for the remainder of this example.

  2. The vdp model appears. You can see each time it is simulated.

  3. The scope window appears. The scope graph changes each time the parameter value changes.

  4. Each component of the report is highlighted as it executes, in the Outline pane on the left in the Report Explorer window.

When the report is complete, Adobe® Acrobat® Reader opens your report in PDF format.
