[scilab-Users] re-delimiting data

[Peng Du]

Thanks Adrien,

The thing confuses me is that the method I used works fine with the
un-processed raw data but fails with the processed file which has
basically the same structure.

And how can I loop through the file if I use the fscanfMat?

Regards,

Peng
