neural network training using matlab

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
