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.

% First Version, 8-31-95.
