SIMULINK model error with 'to file'

A simulink model i created worked fine on my university system and laptop. I then added a few 'to file' blocks (to save on ram during long simulations)to the working model and now this new model runs only on my uni pc.....i get an error when i trying running it on my laptop.....it reads as follows;

block error..source;to file.....Error encountered in block 'tuesday4_2/To File1' model error..source;unknown.....Error opening or closing file 'data.mat'

any idea whats happening and how can i rectify it....thanx.

Answer 1

Seems that you don't have write access to the directory in which mat-files are being written. Open the Matlab as admin try again.

I suggest to change the directory where you are saving your file, if it's in C: do it in D:

[cr28]

the files are being written to the default 'MATLAB' folder in 'Documents' which is definitely C
