1. IN MATLAB Design a Hamming neural network to distinguish between the two vectors : [1;1] and [-1;-1]. Vary each component of the input vector from -1 to 1 in step sizes of 0.2 and check the output (note that this is not strictly speaking a proper use of Hamming networks, which require binary input data). Plot the output of all these points on a 2-D plot using a color coding scheme, i.e., blue if it belongs to class 1 and red if it belongs to class 2.
