satlin

Saturating linear transfer function

Graph and Symbol

Syntax

• A = satlin(N)
  info = satlin(code)
  

Description

satlin is a transfer function. Transfer functions calculate a layer's output from its net input.

satlin(N) takes one input,

• N -- S x Q matrix of net input (column) vectors

and returns values of N truncated into the interval [-1, 1].

satlin(code) returns useful information for each code string:

• 'deriv' -- Name of derivative function.

  'name' -- Full name.

  'output' -- Output range.

  'active' -- Active input range.

Examples

Here is the code to create a plot of the satlin transfer function.

• n = -5:0.1:5;
  a = satlin(n);
  plot(n,a)
  

Network Use

To change a network so that a layer uses satlin, set net.layers{i}.transferFcn to 'satlin'.

Call sim to simulate the network with satlin. See newhop for simulation examples.

Algorithm

satlin(n) = 0, if n <= 0; n, if 0 <= n <= 1; 1, if 1 <= n.
