Derivative of symmetric hard limit transfer function
Syntax
Description
dhardlms
is the derivative function for hardlims
.
dhardlms(N,A)
takes two arguments,
and returns the S
x Q
derivative dA/dN
.
Examples
Here we define the net input N
for a layer of 3 hardlims
neurons.
We calculate the layer's output A
with hardlims
and then the derivative of A
with respect to N
.
Algorithm
The derivative of hardlims
is calculated as follows:
