I expect that the problem is not with reshape.  It looks like the size
of temp is 0x1, so I think the values were not read correctly from the


But the fopen and fread lines are exactly the same for linux and windows.


Have you checked that the file is opened correctly (fid != -1)?

Yes, the file opens correctly. fid = 8

You wrote:

If I don't use ";", The on screen display of the values is correct.
