Convert indices to vectors

Syntax

• vec = ind2vec(ind)
  

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.

ind2vec(ind) takes one argument,

ind	Row vector of indices

and returns a sparse matrix of vectors, with one 1 in each column, as indicated by ind.

Examples

Here four indices are defined and converted to vector representation.

• ind = [1 3 2 3]
  vec = ind2vec(ind)
