satlins (Neural Network Toolbox)

Symmetric saturating linear transfer function

A = satlins(N)
info = satlins(code)

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

satlins(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].

satlins(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 satlins transfer function.

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

You can create a standard network that uses satlins by calling newhop.

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

In either case, call sim to simulate the network with satlins. See newhop for simulation examples.

satlins(n) = -1, if n <= -1; n, if -1 <= n <= 1; 1, if 1 <= n.
