Adding input command to standalone application.

Hi,

I have a 1600 line matlab script that requires several inputs from the user and based on them finds intercept, slope etc and puts them in an excel output file. Few excerpts of my code are below.

prompt = 'What is the input file name (with extension)? ';
inputFile = fullfile(input(prompt,'s'));
prompt = 'Enter 1 or 0';
loop_var = input(prompt);

while (loop_var)
    prompt = 'Enter the name of variable you want to edit';
    new_var = input(prompt,'s');
    
    switch new_var
        case 'slope_threshold' 
            fprintf('Current Value is %f \n', slope_threshold);
            prompt = 'Enter new value';
            residue_threshold = input(prompt);
     %several other variable cases
    end
    prompt = 'If you have more variables to edit enter 1 else enter 0';
    loop_var = input(prompt);
end

My code in command window of Matlab produces the following (user inputs are in bold):

What is the input file name (with extension)? abc.xlsx

Enter output file name, No spaces allowed: abc_output

What is the title of identifying column? Omit Spaces and enter any special chars as _ SERIAL_NO

What is the title of the x axis column? Omit Spaces and enter any special chars as _ TIME

What is the title of the y axis column? Omit Spaces and enter any special chars as _ Acceleration

What is the title of the Group column? Omit Spaces and enter any special chars as _ Group

Here are the parameters being used if you want to change any press 1 else press 0 1

My question is how do I do this in the stand alone application? I keep getting a runtime error if I just convert this m file into an app using the Application Complier.

What does the error say and are you getting this error while compiling or running? Also, how do you expect the user to type answers to the prompt? Did you make some sort of text input box for the GUI ?

Here is the error I got. Line 6 of my code is

inputFile = fullfile(input(prompt,'s'));

I am trying to ask the best practice for it without adding hundreds of additional lines of codes for each potential input. I checked all the Matlab literature for past 5 hours pertaining to this but could not find the example code for something like this.

First I would investigate uigetfile and uiputfile. These are much better ways of having a user enter files to load and save.

You actually don't need fullfile either. That just concatenates parts of a file path. A user can only enter a single string with the input function. There is nothing to concatenate together.

Unfortunately, this doesn't actually answer your question though it may point you to some work arounds.

Thank you your answer pointed me towards inputdlg. Some forums said it wont work but for me it did.

Putting it here for others.

prompt = 'If you want to edit any parameter Enter 1 else Enter 0';
dlgtitle = 'Edit Parameter?';
dims = [1 35];
definput = {'0'};
loop_var  = str2double(inputdlg(prompt,dlgtitle,dims,definput,opts));
% loop_var = input(prompt);

while (loop_var)

        prompt = 'Enter the name of variable you want to edit';
        dlgtitle = 'Variable Editing';
        dims = [1 35];
        definput = {'xxxx'};
        new_var  = char(inputdlg(prompt,dlgtitle,dims,definput,opts));
%         new_var = input(prompt);
        
    switch new_var
        case 'residue_threshold' 
%             fprintf('Current Value is %f \n', residue_threshold);
            prompt = 'Enter new value';
            dlgtitle = 'Variable Editing';
            dims = [1 35];
            definput = {char(residue_threshold)};
            residue_threshold  = str2double( inputdlg(prompt,dlgtitle,dims,definput,opts));
    % other cases
    end
    
    prompt = 'If you have more variables to edit enter 1 else enter 0';
    dlgtitle = 'More Edits?';
    dims = [1 35];
    definput = {'0'};
    loop_var = str2double( inputdlg(prompt,dlgtitle,dims,definput,opts));
end

You can use inputdlg() to enter in all your inputs in just one window - no nead to call it once for every input.
