function [f,x,y] = nnaxclik(a,x,y)
%NNAXCLIK Neural Network Design utility function.

% First Version, 8-31-95.

%	[F,X,Y] = NNAXCLIK(A)
%	  A - Axis handle.
%	Returns:
%	  (X,Y) - Coordinates of last click in axis A coordinates.
%   F     - 1 if (X,Y) is in A, otherwise returns 0.
%
% NNAXCLIK(A,X,Y)
% Returns 1 if (X,Y) is in A, otherwise returns 0.
