You probably don't have fftshow.m on your MATLAB path. This m-file is not part of MATLAB or its toolboxes, but needs to be obtained from somewhere else, such as the File Exchange. Make sure you have downloaded it, and put it in a folder that is on your path.
To check, give the command
which fftshow

use
single(ima_out)
to convert the 'double' to 'single'.

Where is there a version of fftshow that accepts single but not double arguments? Why would anyone write such a thing?
