dsatlin

Derivative of saturating linear transfer function

Syntax

dA_dN = dsatlin(N,A)

Description

dsatlin is the derivative function for satlin.

dsatlin(N,A) takes two arguments,

• N -- S x Q net input

  A -- S x Q output

and returns the S x Q derivative dA/dN.

Examples

Here we define the net input N for a layer of 3 satlin neurons.

• N = [0.1; 0.8; -0.7];
  

We calculate the layer's output A with satlin and then the derivative of A with respect to N.

• A = satlin(N)
  dA_dN = dsatlin(N,A)
  

Algorithm

The derivative of satlin is calculated as follows:

• d = 1, if 0 <= n <= 1; 0, otherwise.
