How to use NNTOOL

I am using nntool to build and train my network, my question if I have the input has 300 elements how they sent to the network if I have 50 input neurons ?. are they sent from 1 - 50 then 51 to 100 then 101 to 151 ..etc or 1 - 50 them 2 - 51 then 3 - 52

ANN is a system of parallel distribution,hence there is no such qns as you are perceiving. In my view the input data having any no of input neuron and corresponding elements will be sent simultaneously to the next layer.

If the input has 300 hundred elements, and the hidden layer has 50 neurons, then each of the 300 neurons will have a connection each of the 50 neurons, for 15,000 total connections with adjustable weight values.

There will also be a connection each of the 50 neurons to the output. If the output has two elements for instance, that will mean another 100 connections, each with an adjustable weight.

If a feedforward network is created with more than one hidden layer, each neuron of a preceding layer will be connected to each neuron in the following layer.
