convol2ddiscrete 2-D convolution, using fft. SyntaxC = convol2d(A,B)ParametersA
a real or complex 2-D array.
B
a real or complex 2-D array.
C
a real or complex 2-D array.
Descriptionconvol2d uses fft to compute the full
two-dimensional discrete convolution. The
dimensions of the resultC are given by
size(A)+size(B)+1. The indices of the
center element of B are defined as
floor((size(B)+1)/2).
