There is an issue regarding the sampling with this approach. Since the code simply samples the closest value the result is heavily undersampled in some regions (r>>), while it is oversampled in others (r<<).
It would be interesting to have a correct approach that satisfies signal processing criteria (e.g. smooth oversampled regions and grey values where undersampled black and white values come together.
Where is the function iapolarcoord ? This function is named as imgpolarcoord and it need three input.Is the other two inputs(radius and angle) don't need to enter?
%pcimg=iapolarcoord(im);-' it should be %pcimg=impolarcoord(im);
% fpcimg=iapolarcoord(fim);'it should be % fpcimg=impolarcoord(fim);
BOTH OF THEM DOES NOT WORK
%pcimg=iapolarcoord(im);-'
%pcimg=impolarcoord(im);
ANY ONE KNOW THE CORRECT CODE??

It is an excellent code. I tested it.
Thank you very much, and if you have other codes please upload them!!
There is a typo in the example, at the third and fourth lines.
%pcimg=iapolarcoord(im);-' it should be %pcimg=impolarcoord(im);
% fpcimg=iapolarcoord(fim);'it should be % fpcimg=impolarcoord(fim);
