About weights of neural network

I make a neural network, and I used the following data.

Nodes No. of input data = 1016 // Nodes No. of hidden layer = 10

but, net.IW{1,1} matrix is {10x851} double matrix, not {10x1016}.

Why is this?

Input data has the same number or a little bit of 0.

And how can I calculate directly from these weights matrix?
