Convolution

convolve3(M, K) Returns the quick convolution of matrix M with 3 × 3 kernel K.

convolve5(M, K) Returns the quick convolution of matrix M with 5 × 5 kernel K.

convol2d(M, K) Returns the convolution of matrix M with kernel K.

Arguments:

• M is an image matrix.
• K is a kernel matrix of a size appropriate to the function called. Elements are real numbers.
