[imagefile] = imread([direktori,namafile],'bmp');

WHAT IS THIS NET SUPPOSED TO DO?
WHATEVER IT IS P AND T SHOULD NOT BE EQUAL.
PLEASE EXPLAIN P,T AND THEIR DIMENSIONS.
[pn,meanp,stdp,tn,meant,stdt]=prestd(P,T)
net=newff(minmax(pn),[4,3,1], {'tansig' 'logsig' 'purelin'},'traingdm');
YOU ONLY NEED ONE HIDDEN LAYER.
CHOOSE THE NUMBER OF HIDDEN NODES BY TRIAL AND ERROR.
SEARCH THE NEWSGROUP USING
HEATH NEQ NW
FOR A 1-D OUTPUT SIZE(T) = [ 1 N ]
net.IW{1,1}
net.b{1}
net.LW{2,1}
net.b{2}
net.LW{3,2}
net.b{3}
net.trainParam.lr = 0.1
net.trainParam.goal = 0.00001
net.trainParam.epochs = 500
net.trainParam.show = 500
IT IS USUALLY BEST TO BEGIN WITH DEFAULTS AND THEN CORRECT AS NEEDED.
net=train(net,P)
NO. YOU HAVE STANDARDIZED THE INPUTS. THEREFORE USE pn.
but when i write this code "net=train(net,P)" , the result is nothing, even out of debug mode,
HARD TO COMMENT ON THAT UNTIL YOU MAKE THE ABOVE CORRECTIONS.
P.S. i DID NOT CHECK THE FIRST 3 COMMANDS. SO, DO SO BEFORE RERUNNING,
HOPE THIS HELPS.
