Abs

Function Abs

The Abs function computes the absolute value 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	1.80	1.79	0.82
	LA	1.80	1.79	0.82
	EP	1.80	1.79	0.82
double	HA	2.19	2.10	0.88
	LA	2.19	2.10	0.88
	EP	2.19	2.10	0.88

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.
