Open MATLAB function report
openReport( opens the MATLAB® function report for a MATLAB Function block.config)
The first time that you open the MATLAB function report, Simulink® automatically updates your model. If you make subsequent changes to the MATLAB code in the block, you must update your model before you reopen the report. Otherwise, the report does not reflect your changes. From the Modeling tab, select Update Model, or press Ctrl-D. For more information, see Update Diagram and Run Simulation.
