Saturating linear transfer function

Graph and Symbol

Syntax

A = satlin(N,FP)

Description

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

A = satlin(N,FP) takes one input,

N

S-by-Q matrix of net input (column) vectors

FP

Struct of function parameters (ignored)

and returns A, the S-by-Q matrix of N's elements clipped to [0, 1].

info = satlin('code') returns useful information for each supported code string:

satlin('name') returns the name of this function.

satlin('output',FP) returns the [min max] output range.

satlin('active',FP) returns the [min max] active input range.

satlin('fullderiv') returns 1 or 0, depending on whether dA_dN is S-by-S-by-Q or S-by-Q.

satlin('fpnames') returns the names of the function parameters.

satlin('fpdefaults') returns the default function parameters.

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)

Assign this transfer function to layer i of a network.

net.layers{i}.transferFcn = 'satlin';
