Hi! I have this cell. How can I determine the coordinates where the 0's are?
For example in 'matrix' I need to get a matrix with the coordinates (2,2) and (1,4):
matrix = importdata("matrix.mat");
out = [2,2; 1,4];

Ran in:
Why storing scalars in cell and not in matrix? It is very inefficient.
load matrix
check_1
check_1 = 4×2 cell array
{[1]} {[1]} {[1]} {[0]} {[1]} {[1]} {[0]} {[1]}
[i,j]=find(cellfun(@(x) isequal(x,0), check_1));
ij = [i,j]
ij = 2×2
4 1 2 2
