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 =

Any idea how to get the "3 1 2"?

Thank you

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.
