SETDEFAULTS

Set defaults for function parameters

    ARGOUT = SETDEFAULTS(ARGIN,DEF1,DEF2, ....)
    [P1,P2, ...] = SETDEFAULTS(ARGIN,DEF1,DEF2, ....)

Input
ARGIN	Cell array with function input arguments, typically VARARGIN
DEF1	Default value for argument 1
DEF2	Default value for argument 2

Output
ARGOUT	Cell array defaults replacing the empty input arguments
P1	Input argument 1, replaced by its default if empty
P2	Input argument 2, replaced by its default if empty

Description

This routine substitutes empty input parameters of a function (typically  given by VARARGIN) with the defaults DEF1, DEF2, etcetera.
