MATLAB: Custom NN in matlab

neural network

Hello, I'm quite new to matlab, I need to create my own custom neural network using m-file with pre-defined weights. Problem is, that I need 5 inputs and 5 outputs, when using newff(parameters) always get 2 outputs and so many inputs what is the size of input data vector. Please help me with this, thx!

If you have N I/O pairs with I-dimensional input vectors and corresponding O-dimensional output target vectors, the size of the input and target matrices are

[ I N ] = size(x) %input

[O N ] = size(t) % target

Hope this helps.

To get N "O"utput vector dimensions of O corresponding to N "I"nput vector dimensions of I, the sizes of the input and target matrices should be

 [ I N ] = size(input)
 [O N ] = size(target)

Hope this helps.

MATLAB: HOW to use NN tool in MATLAB ? and then what are input to give

You have to define the "I"nput matrix, x, with size I x N consisting of N I-dimensional input vectors and corresponding "O"utput target matrix, t, with size O x N consisting of N O-dimensional output target vectors. After training, the resulting output matrix, y, will have the same dimensions as the target matrix.

For beginners, it is recommended to begin with the regression/curve-fitting function FITNET and SISO function defined by 1-dimensional matrices with I=O=1.
