nndhopi.m

Neural network design中的网络构建 包括结合MINI神经网,网络布局,声音,颜色的选择,存在,培训,分类,收缩,以及读写,标记等功能的编程

function yprime = nndhopi(t,y)
%NNDHOPI Calculates the derivative for sample Hopfield network
%
% NNDHOPI(t,y)
%   t - Current time
%   y - Current output
% Returns dy

global W;
global b;

% Assuming infinite Lambda:

yprime = 0.5*W*y;
