Powx
Raises each element of a complex vector to the constant power, that is, computes
a
to power b
, where b
is a scalar.Performance:

Notes:
- Units - CPE (Clocks per Element)
- Performance was measured on "working" interval (double precision: [ 0.01, 20.0 ] × [ 0.01, 20.0 ]; single precision: [ 0.01, 20.0 ] × [ 0.01, 20.0 ])
- Data - vectors of 1000 elements with random generated numbers.
- All data was collected with 64-bit libraries.
