formx

Form bias and weights into single vector

Syntax

• X = formx(net,B,IW,LW)
  

Description

This function takes weight matrices and bias vectors for a network and reshapes them into a single vector.

X = formx(net,B,IW,LW) takes these arguments,

• net -- Neural network

  B -- Nlx1 cell array of bias vectors

  IW -- NlxNi cell array of input weight matrices

  LW -- NlxNl cell array of layer weight matrices

and returns,

• X -- Vector of weight and bias values

Examples

Here we create a network with a two-element input, and one layer of three neurons.

• net = newff([0 1; -1 1],[3]);
  

We can get view its weight matrices and bias vectors as follows:

• b = net.b
  iw = net.iw
  lw = net.lw
  

We can put these values into a single vector as follows:

• x = formx(net,net.b,net.iw,net.lw))
