how to return indices?
1 view (last 30 days)
I have a 3 dimensional data matrix (72*45*2109), and I need to extract all data less than 15. the final output should be a 3d matrix
I used the following lines, but the result is a vector. The point is to return the indices to have 3d matrix.
Any help would be greatly appreciated.
[r,c,v] = ind2sub(size(data),find(data >= 15));
l = data(sub2ind(size(data),r,c,v));
