ISXYZ

Purpose:

Returns 1 if input parameter is an XYZ series.

Syntax:

ISXYZ(val)

val

-

A series, scalar or string value to test.

Returns:

The scalar 1 if the input is an XYZ series, else 0.

Example:

s1 = gsin(100, 1/100);

s2 = gcos(100, 1/100);

s3 = 1..100;

s4 = xyz(s1, s2, s3);

 

isxyz(s1) == 0

isxyz(s2) == 0

isxyz(s3) == 0

isxyz(s4) == 1

Example:

isxyz(3)

 

returns 0

Remarks:

If the input is not a series, isxyz returns 0.
