vec2ind
vec = [0 0 1 0; 1 0 0 0; 0 1 0 0]'
vec =
0 1 0
0 0 1
1 0 0
0 0 0
[ind,n] = vec2ind(vec)
ind =
3 1 2
n =
4
Any idea how to get the "3 1 2"?

The first transposition gets the values for the columns (rather than rows), then the second transposition creates ‘L’ to be the same dimensions ‘T’ originally is.
