If you have N samples of I features, the size of the input matrix is

[ I N ] = size(input)

The size of the corresponding target matrix for c classes is

[ c N ] = size(target)

The target columns are columns of the c-dimensional unit matrix eye(c) with the row index of the 1 indicating the class index of the corresponding input vector.

See the classification/pattern-recognition demos using patternnet.

Hope this helps.
