Homework Help: Constructing neural netowrk (perceptron)

  1. Mar 20, 2007 #1
    1. The problem statement, all variables and given/known data
    Implement (AND, NAND) gates using MATLAB.


    2. Relevant equations



    3. The attempt at a solution
    I've succeeded to implement a single perceptron that has a single output and multi inputs.
    Here is the code I've written
    --------------------------------------------------------------------------
    P = [0 0 1 1;0 1 0 1] %Pattern
    T = [0 0 0 1] %Target
    net = newp(minmax(P),1)
    net = train(net,P,T)
    --------------------------------------------------------------------------
    I need two output terminals, AND results goes to the first terminal and the inverted AND (NAND goes to the other terminal).
    I've referred to MATLAB help



    Description


    train trains a network net according to net.trainFcn and net.trainParam.

    train(net,P,T,Pi,Ai,VV,TV) takes

    netNetworkPNetwork inputsTNetwork targets (default = zeros)PiInitial input delay conditions (default = zeros)AiInitial layer delay conditions (default = zeros)VVStructure of validation vectors (default = [])TVStructure of test vectors (default = [])


    When I tried to rewrite my code with a 2 row target matrix I've got an error as follows

    P = [0 0 1 1;0 1 0 1] %Pattern
    T = [0 0 0 1;1 1 1 0] %Target
    net = newp(minmax(P),1)
    net = train(net,P,T)

    ??? Error using ==> network.train
    Targets are incorrectly sized for network.
    Matrix must have 1 rows.

    Error in ==> AndGate at 4
    net = train(net,P,T)

    My question is, how can I set two output terminals instead of single output terminal? as I need one terminal for AND gate and the other for NAND gate.

    Thanks.
