Hi friends,

I get the following error while trying to use neural network toolbox in matlab. I am new to its use, thereby any help would be crucial.

Here are my codes

Basically I have a vector (1X75) as the input and to it I have two outputs, thereby I have created one loop to repeat the same value to for each input. *

I get the following error :

Error using trainlm (line 109)
Input data size does not match net.inputs{1}.size. *
% My codes 
load data 
I=data'; % 1 X 75 row vector
for i = 1 : length(data)
    z(1,i) = 0.0029;
    h(1,i) = 20;
end
O= [z;h]; % 2 X 75 vector
R=[0 1; 0 30 ]; % limits for the two ouput values
S=[5 2]; % No of inner  and output neurons  
   net = newff(R,S,{'tansig','purelin'}); 
   net=train(net,I,O);
