Store into .MAT file??

Answer 1

As binary file:

X = rand(3, 4, 5);
save('FileName.mat', 'X');

As text file:

FID = fopen('FileName.txt', 'w');
if FID == -1, error('Cannot create file.'); end
fprintf(FID, '%g %g %g\n', X);
fclose(FID);

You find more examples in the documentation.

Try to use the function dlmwrite.

@huda nawaf: The saved file *is* properly, but your expectations are not matching. FPRINTF writes the elements columnwise, as expalined in the documentation repeatedly. If you want x appear as in the command window:

fprintf(FID, '%g %g %g %g %g\n', transpose(x));

Of course the format string '%g %g %g\n' is *not* thought for a [5x5] matrix.
