dsatlin (Neural Network Toolbox)

Derivative of saturating linear transfer function

dA_dN = dsatlin(N,A)

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)

The derivative of satlin is calculated as follows:

d = 1, if 0 <= n <= 1; 0, Otherwise..
