hy guys,
i would like to deconvolute a matrix but i didn't find a 2d deconvolution function , any idea how to do that without using fft or ifft?
thank you in advance
code:
clear all
clc
a=randi(2,3)
b=randi(2,3)
c=conv2(a,b)
% [d,r]=deconv2(c,a) this is what i would like to get
subplot(221)
img(a)
subplot(222)
img(b)
subplot(223)
img(c)
subplot(224)
img(d)

Using
a=randi(2,3);
b=randi(2,3)
c=conv2(a,b);
M=func2mat(@(x) conv2(a,x), zeros(3));
b_recon=reshape(M\c(:), 3,3)
