Question

MATLAB中postreg函数如何使用，能提供简单例子吗，谢谢

Answer 1

p = [-0.92 0.73 -0.47 0.74 0.29; -0.08 0.86 -0.67 -0.52 0.93];
t = [-0.08 3.4 -0.82 0.69 3.1];
[pn,meanp,stdp,tn,meant,stdt] = prestd(p,t);
[ptrans,transMat] = prepca(pn,0.02);
net = newff(minmax(ptrans),[5 1],{'tansig''purelin'},'trainlm');
net = train(net,ptrans,tn);
an = sim(net,ptrans);
a = poststd(an,meant,stdt);
[m,b,r] = postreg(a,t);
