The error function doesn't work with me. I do not get any result.
If anyone knows the problem, I will be thankful
for j1=1:3,
yi=w'*x(:,j1); % Network output
y=sign(yi);
if sum(y-d(1,:)') > 0
error=error+1
end
end

It is very unlikely that the code shown does whatever it is required to do. The whole thing doesn't make sense. Of course, if the code was commented as it should be, we would have an idea of what it was supposed to do (hint!).
Note:
Madhan: size(y) is 4 by 1
Amna: size(y) is 4 by 3
size(y) is always going to be size(w, 2) by 1. It can't have 3 columns since the multiplication in w' * x(:, 1) guarantees it will have one column. It will has as many rows as w has column, which is no whose value was not given. If no is 3 the subtraction will succeed. ni has to be 4 for the multiplication to work.
Also note that naming a variable error is a bad idea. It's already the name of a matlab function.
