@minutiae can you correct the code?
Two errors in the algorithm:
1. fftshift was not used to center the DFT of image
2. zero padding was not performed.
what d stands for in this function? I guess r is the rows , c is the columns and n is the order. How does n affect the final output? Can you be more descriptive for beginners?
??? Error using ==> times
Matrix dimensions must agree.
