Apple's Accelerate vDSP : How to get the argument of complex vector from FFT

Question

vDSP allows computing the result of the Discrete Fourier Transform as a complex vector.

The function vDSP_zvmags provides the squared norm of the complex vector. How can I compute the argument (or should I do it myself by hand)?

Answer 1

I think what you want is vDSP_zvphas
