when i train this network i get errors
please help me
clc
clear
close all
p=[1:10 10:10:100];
t= (p.^2);
net=newff(p,t,[3], {'logsig' 'purelin'});
net.divideParam.trainRatio=1;
net.divideParam.testRatio=0;
net.divideParam.valRatio=0;
net.divideParam.lr=0.01;
net.divideParam.min_grad=1e-20;
net.divideParam.goal=1e-30;
net.divideParam.epochs=300;
net=train(net,p,t);
plot([1:100] .^2,'x')
hold on
plot(round(net(1:100)),'o')
plot(p,t, '*g')
legend('real target', 'output of net', 'training samples', 'location', 'north west')
the error msgs are:
Warning: 'min_grad' is not a legal parameter.

although i defined the epochs to 300 while training continues to reach 1000 epochs
i do not know why ? pls help me

min_grad appears to be for trainFcn not for divideParam
