Number of output arguments for System object

Syntax

Description

[numOutputs](#d126e2109406) = nargout([obj](#d126e2109377)) returns the number of output arguments that are required by the obj algorithm definition. This function is a System object™ extension of the general nargout function.

If the System object does not override getNumOutputsImpl and thestepImpl signature contains varargout, then nargout returns the negative of the number of outputs. For example, ifstepImpl declares outputs y,z, and varargout, thennargout(obj) returns -3.

nargout returns the number of output arguments specified in the call to the currently executing System object. Use this syntax in the body of a System object only.
