CIS

Function CIS

The CIS function computes a complex exponent of real vector elements (cosine and sine of real vector elements combined to a complex value).

Performance:

	EP	35.37	32.03	112.54

Notes:
1) Units - CPE (Clocks per Element)
2) Performance was measured on "working" interval (double precision: [-10000.0 ; 10000.0]; single precision: [-10000.0 ; 10000.0])
3) Data - vectors of 1000 elements with random generated numbers.
