How to update .mat file in simulink.

Hello,
I have a Matlab function block which loads a variable from a .mat file and work on it. I then updates the variable and then returns the value to a 'To File' block in simulink which saves the variable by the same name.
But every time I run the simulation, it creates a new .mat file by the same name with null value. Is there a solution for that?
I want to access the variable, change its value and then save it again by the same name.
Thanks for the help.

What is the reason running it in Simulink? Keep in mind that the MATLAB Function block is executed every simulation step, e.g. 0.01 seconds.

To File block creates a duplicate file every time the simulation happens.
A possible workaround would be to use Input and Output blocks instead.
- Assign the same variable names to both input and output.
- Load and Save the MAT-file containing the variables using callback functions.
