Number of expected inputs to step method

Syntax

N = getNumInputs(H)

Description

N = getNumInputs(H) returns the number of expected inputs, N to the step method.

The getNumInputs method returns a positive integer that is the number of expected inputs (not counting the object itself) to the step method. This value will change if you alter any properties that turn inputs on or off. You must call the step method with the number of input arguments equal to the result of getNumInputs(H).
