I have a matrix [640 640] with few non zero values and many zeros. I want to put all the non zero values in a new matrix. Something like:
for i=1:640
for j=1:640
if A(i,j)~=0
B(i,j)=A(i,j)
end
end
end
But this doesn't work.. Any suggestions?

What do you mean doesn't work. There is an easy way to do it which uses logic index. What value do you want for other elements in B?
