Function Abs

 

The Abs function computes the absolute value of complex vector elements.

 

Performance:

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.
