I am trying to save the entries of a 1by 5000 cell array but keep receiving this warning message: "Warning: Variable 'new_X' cannot be saved to a MAT-file whose version is older than 7.3. To save this variable, use the -v7.3 switch. Skipping..."
I checked the version which is 126.96.36.1994 (R2010b). Even if I try saving it manually, the size of the saved file is too small (128 bytes) and over that it does not even open up.
