How do use the newgrnn function for 5 featured data?

when i was using this newgrnn function matlab was showing an error.. inputs is a matrix of dimensions 2000x5 and output is a matrix of dimensions 2000x1.. this was the error which i got.. anyone please help.. thanks

 >> net=newgrnn(inputs_train,AQI_train)
Error using network/subsasgn>network_subsasgn (line 528)
net.IW{1,1} must be a 1-by-2000 matrix.

Error in network/subsasgn (line 13) net = network_subsasgn(net,subscripts,v,netname);

Error in newgrnn>create_network (line 123) net.iw{1,1} = p';

Error in newgrnn (line 67) net = create_network(param); end

In most NN Toolbox functions: For N pairs of I-dimensional "I"nputs and corresponding O-dimensional "O"utput targets

 [ I N ] = size(input)

and

 [ O N ] = size(target)

Hope this helps

Thank you for formally accepting my answer

thank you greg, could you please tell how should my parameters passed to the newgrnn function when the inputs are as mentioned in the question?

Exactly as shown in the documentation

 help newgrnn

and

 doc newgrnn

Hope this helps.

Thanks for the reply Greg. In the documentation it is said that net=newgrnn(x,y,spread) where x(input) is a AxN matrix and y(target) is a BxN matrix. when the network is trained we can simulate the network using a= sim(net,input); when i do this the prediction by matlab is not matching with the training data itself. Please help me.
