function h=nndtext(t,x,y,a)
%NNDTEXT Neural Network Design utility function.

%	NNDTEXT(T,X,Y)
%	  T - Text (string).
%   X - Horizontal coordinate.
%   Y - Vertical coordinate.
%   A - Horizontal alignment (default = 'center').
% Draws text T at location (X,Y) in bold and NNDKBLUE and
% erasemode of 'none'. Optionally returns handle to text.
