File access from s-function

Is it possible use file functions from a s-function on a windows PC?

I would like to store and read array information on the PC harddive.

I have attempted to use standard fopen function inside the .cpp file but the matlab enviroment crashes.

Hello,

As per my understanding, you want to perform file operations like reading a file from S-Function.

To read data from a text file, you can write your own S-Function.

Please check the following MATLAB Answer which answers the similar question:

I hope this resolves the issue you are facing.

I would like to use the fopen function directly from a S-function.

Matlab crashes when I try this from a S-function.

How do I do this without matlab crashing?
