Inv

Function Inv

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

Performance:

		Dual-Core Intel(R) Xeon(R) processor 5100 Series	45nm Intel(R) Core(TM)2 Duo processor	Intel(R) Itanium(R) 2 processor
single	HA	4.45	2.87	3.21
	LA	2.04	1.99	3.21
	EP	1.46	1.40	3.20
double	HA	9.65	6.14	4.42
	LA	7.85	6.14	4.21
	EP	7.83	6.11	4.20

Notes:
1) Units - CPE (Clocks per Element)
2) Performance was measured on "working" interval (double precision: [ 0.0001, 10000.0 ]; single precision: [ 0.0001, 10000.0 ])
3) Data - vectors of 1000 elements with random generated numbers.
