neural network - How can I modify my code to show training and testing graphs in MATLAB? -

-

i have code neural networks. how can modify code can show training , testing graphs?

%~~~~~~~~~~~[l1 l2 1];first hidden layer,second & output layer~~~~~ layer = [11 15 1]; myepochs = 30; attemption = 1; %i; mytfn = {'tansig' 'tansig' 'purelin'};  %~~~~~~load data~~~~~~~~~~~~~~~~~~~~~~~ m = xlsread('c:\documents , settings\winxp\my documents\matlab\matlab_data\datatrain.csv');     %~~~~~~convert data in matrix form~~~~ [row,col] = size(m);            p = m(1:row,1:10)';  t1 = m(1:row, col)';   % target data training...last column  net = newff([minmax(p)],layer,mytfn,'trainlm');  %nnet  net.trainparam.epochs = myepochs;   % how many time newff repeat training net.trainparam.showwindow = true; net.trainparam.showcommandline = true; net = train(net,p,t1);  % start training newff input p , target t1  y = sim(net,p);   % training  save 'net114' net;

also, code correct? want calculate area , perimeter of image. calculated values show perimeter bigger area not make sense, right? or maybe maybe there's explanation that?

bw =~c; area= bwarea(bw); area imshow(bw);  bw2=~c;  pm=bwperim(bw2); perimeter=bwarea(pm);

you might want try net.trainparam.show = 30 show training progress every 30 epochs.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
