Sigmoid

Sigmoid passes input through a sigmoid function of the form:

out1 = 1/(1+exp(-X.in1))

The parameter X controls the slope of the sigmoid.

X can either be a constant specified by the block's parameter, or a time varying signal fed to the block via the optional input in2.

Inputs	Meaning	Sample	1-D frame	2-D frame
in1	signal	Yes	Yes	Yes
(in2)	dynamic X parameter	Yes	Yes	Yes

Outputs	Meaning
out1	input after passing through sigmoid

Parameters	Type	Default	Meaning
X	Float	-	The sigmoid slope parameter
