Hi Disheng,
I understand that you would like to know how to export an array with a variable output size in Simulink. Please elaborate on the desirable format for export. In the meanwhile, the process to write numeric and text data to a spreadsheet file is as follows:
writecell(C,filename)
The above command, when used in a MATLAB function block, writes to a file with the name and extension specified by filename. ‘writecell’ determines the file format based on the specified extension. The extension must be one of the following:
- .txt, .dat, or .csv for delimited text files
- .xls, .xlsm, or .xlsx for Excel spreadsheet files.
If the array is populated, Simulink will export the array irrespective of the size.
To learn more about exporting an array, please refer to the below documentation:
I hope this helps!
