Variable Name	Size	Description
x	double	Independent variable in the function.
x0	double	Offset in the independent variable x.
a	double	Amplitude of the harmonic function.
w	double	The frequency of the harmonic function.
phi	double	Phase shift in the harmonic function.
b	double	Average displacement of the harmonic function.
order	int	1) order = 0 2) order = 1 3) order = 2
value	double	1) order = 0 2) order = 1 3) order = 2
errflg	logical	If an error is encountered in invoking Predefined subroutine, this variable becomes true. This variable must be declared as a logical variable.
