ISXYZ

Purpose:

Returns 1 if input parameter is an XYZ series.

ISXYZ(val)

val

A series, scalar or string value to test.

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

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

isxyz(3)

returns 0

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