You need to call the function fftenhance with an input image. For example
image = imread('pears.png'); % name of an image file
fftenhance(image, 2)
Save your function in a file named fftenhance.m, and then run the above two lines in command window.

You need to make sure your function is on the Matlab path or in your current folder.
What does this line return as output?
clc,disp(pwd),which fftenhance -all
And what exact folder did you save the fftenhance.m file?
