hi i has this data set at input o=[0 5 10 15 20 25 30 ] and my target data which it two output t=[0.5 0.5 0.3 0.23 0.45 0.35 0.34 0.7 0.4 0.2 0.5 0.23 0.34 0.45] i want learn my network which it feed-forward with any algorithm 2 hidden layer and one output layer thank in advance m,s

You only need 1 hidden layer. Therefore, I assume you mean H = 2 hidden nodes in that hidden layer. For an I-H-O feedforward network to be trained with N I-dimensional inputs and N corresponding O-dimensional outputs, your input matrix, x, and your target matrix, t sould have the following dimensions

[ I N ] = size(x)

[ O N ] = size(t)

See the documentation example for the rest

Hope this helps.

Thank you for formally accepting my answer.
