Rasing complex numbers to a (real) power

[adi_shavit]

Hi,

I have a vector of complex numbers.
Is there a fast way to raise it some some real power?
Is there a complex pow() function?

If not, then how can I simulate one using IPP functions?

Thanks,
Adi

Hi Adi,

long time did not hear you, hope you are doing well. By the way, you probably noticed increased number of IPP functions which support 16-bit data type in the latest versions of IPP.

I've submitted your feature request to Intel Premier Support, so you will be notified about updates on it.

Regards,
Vladimir

Hello Adi,

This is Ying, IPP support. I recieve your request from Vlad. I'm not sure if you can access <>, which is our official support channel. So I share some information with you here.

Regarding the function of pow() or powx(), maybe you can try

IppStatus ippsPow_32f_A11

IppStatus ippsPow_32fc_A11

in ipps domain.

You can see more functions on the section of Fixed-Accuracy
Arithmetic Functions in ipp manual ippsman.pdf .

Please let me know if these funtions can meet your requirement.

Regards,

Ying
