I have trained the model on input having

size(input) = [1 78852] double

and output of

size(Output) = [1 78852].

The model is trained using command

net = layrecnet(1:2,[20 20],'trainlm');.

I want to use the predict(net, X) but it is giving me error

Error using predict (line 84)
No valid system or dataset was specified.

As my input is single dimentional vector. How to use this predict function in my prgoram?

How do you expect us to help when you do not show us your code ???
Just the fact that the error involves "predict" and you show no such code is more than enough for a bald man to scratch his head.
Please see the HELP and DOC files before posting a question.

From help and Doc I was on conclusion that my input is single dimentional vector and in predict() function need the matrix of D-by-S matrix if data is sequential. So, I have tried the alternate way of argument in the funtion. But gettting the same resulted error.

YPred = predict(net,[Input_validation_data(1:10), 11] );
