Cbrt

Function Cbrt

The Cbrt function computes a cube root of real vector elements.

Performance:

		Intel(R) Xeon(R) processor 5100 Series	45nm Intel(R) Core(TM)2 Duo Processor	Intel(R) Itanium(R) 2 processor
single	HA	10.76	9.29	7.18

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.
