getNumOutputs

Number of outputs from calling the System object

Syntax

num = getNumOutputs(obj)

Description

num = getNumOutputs(obj) returns the number of outputs, num, from calling the object. This value changes when you alter properties that turn outputs on or off.

If the object is a sink object, num equals zero.

Examples

Get Number of Outputs for an Object

Create a Counter object and set a property.

obj = Counter;
obj.UseIncrement = false

obj = 
  Counter with properties:

    UseIncrement: 0
    UseWrapValue: 1
      StartValue: 1
       Increment: 1
       WrapValue: 10

Get the number of inputs and outputs needed to call the object.

in = getNumInputs(obj)

in = 1

out = getNumOutputs(obj)

out = 1

Input Arguments
