vec2ind (Neural Network Toolbox)

Convert vectors to indices

ind = vec2ind(vec)

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 1's.

Examples

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

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