Whit command mapminmax

load datoscompletos.txt datoscompletos; p=datoscompletos(:,1:4)'; t=datoscompletos(:,5:6)'; [p1,ps1]=removeconstantrows(p) [pn,ps2] = mapminmax(p); [tn,ts] = mapminmax(t); pr=minmax(pn); s2=size(tn,1); net = newff(pr,[10 20 15 20 2],{'tansig' 'tansig' 'tansig' 'tansig' 'purelin'}); net.trainParam.show = 40; net.trainParam.lr = 0.1; net.trainParam.epochs = 100; net.trainParam.goal = 0.01; net.trainParam.min_grad = 0.0000001; net = train(net,pn,tn); Yred = sim(net,pn); a = mapminmax('reverse',Yred,ts);
