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 $\ge$2-D frame
in1 signal Yes Yes Yes
(in2) dynamic X parameter Yes Yes Yes

Outputs Meaning
