Hi everyone,
I have an error in that line:
net=newff(minmax(p),[3,1],{'tansig','purelin'},'trainlm')
And this error 'minmax' requires Deep Learning Toolbox.
Can someone help me? Thanks!
clear all
load zad2.mat
k=1; n=length(x);
for i=1:n
for j=1:n
z(i,j)=u(i,j);
p(1,k)=x(i);
p(2,k)=y(j);
t(k)=z(i,j);
k=k+1;
end
end
figure(1), mesh(x,y,z);
net=newff(minmax(p),[3,1],{'tansig','purelin'},'trainlm');
net.trainParam.epochs=100;
net=train(net,p,t);
for i=1:n
for j=1:n
y(i,j)=sim(net,[x(i);y(j)]);
end
end
figure(2),mesh(x1,x2,y)

This error message tells you that you don't have the required package installed in order to use the minmax() function.
Matlab comes with a lot of functions. But for some speciallized topics there are packages (or expensions) you can buy in order to enhance matlab's capabilities. Minmax() seems to be one of those specialized functions that are part of the Deep Learning toolbox package.
