function y = nnpin(x,a,b,q)
%NNPIN Neural Network Design utility function.

%  NNPIN(X,A,B,Q)
%    X - Number or matrix.
%    A - Lower bound.
%    B - Upper bound.
%    Q - Quantization constant (optional).
%  Returns values in X pinned into the interval defined
%  by A and B and rounded to the nearest multiple of Q.
