Convert vectors to indices

Syntax

• ind = vec2ind(vec)
  

Description

ind2vec and vec2ind allow indices to be represented either by themselves or as vectors containing a 1 in the row of the index they represent.

vec2ind(vec) takes one argument,

vec	Matrix of vectors, each containing a single 1

and returns the indices of the 1s.

Examples

Here four vectors (each containing only one "1" element) are defined, and the indices of the 1s are found.

• vec = [1 0 0 0; 0 0 1 0; 0 1 0 1]
  ind = vec2ind(vec)
