Inv

Function Inv

The Inv function performs element by element inversion of the real vector.

Performance:

		Intel(R) Xeon(R) processor 5100 Series	45nm Intel(R) Core(TM)2 Duo Processor	Intel(R) Itanium(R) 2 processor
single	HA	4.36	3.10	3.13
	LA	3.06	1.96	3.13
	EP	1.37	1.36	3.13
double	HA	10.12	5.70	4.34
	LA	6.70	5.70	4.14
	EP	6.50	5.70	4.14

Notes:
1) Units - CPE (Clocks per Element)
2) Performance was measured on "working" interval (double precision: [ 0.1 ; 10000.0 ]; single precision: [ 0.1 ; 10000.0 ])
3) Data - vectors of 1000 elements with random generated numbers.
