+% PROFILERTOEXCEL Convert Simulink Profiler data into an Excel spreadsheet.
+% Currently, the Simulink Profiler only supports exporting data to a MAT file.
+% You can load the MAT data into your workspace, and then use this script to
+% convert it into an Excel file.
+%
+% For more information about the Simulink Profiler, see:
+% https://www.mathworks.com/help/simulink/slref/simulinkprofiler.html
+%
+% Inputs:
+% profileData Simulink.profiler.Data object.
+% filename Desired Excel filename.
+%
+% Outputs:
+% N/A
+%
+% Side Effects:
+% Excel file created in the present working directory.
+%
+% Example:
+% profilerToExcel(profileData, 'text.xlsx');
