ind2vec (Neural Network Toolbox)

Convert indices to vectors

vec = ind2vec(ind)

ind2vec and vec2ind allow indices to either be represented 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)
