MATLAB: How to find zeros of a matrix

Question

I learn me better

for example, given A

A=[1     2     3     0     0     5; 8     0     3     0     9     9]

I want a vector which contains the extrems of these zeros:

v=[3 5; 8 3; 3 9];

thanks

Answer 1

A = [1,2,3,0,0,5;8,0,3,0,9,9];
AA = A';
AA = AA(:)';
lo = AA ~= 0;
out = AA([strfind(lo, [1 0]);strfind(lo, [0 1])+1]');
