Single Perceptron Learning

Without using inbuilt functions from NN Tool. Perceptron learning is implemented.

Perceptron Learning Rule is:
% Wnew = Wold + e*p
% e = t - a
% b = bold + e
% Update the weight & bias until it prodeuces correct target for inputs.

% For example:
% And Gate:
% P=[0 0 1 1; 0 1 0 1]; t=[0 0 0 1]; w=[0 0]; b=0; ep=20;
% [w b]=perceplearn(P,t,w,b,ep);
