This manual is preliminary and incomplete.
While our Core implementation implements all functions given in the standard we are still working on completing this documentation.

Please refer to the VSIPL standard for a complete function reference of the Core profile until we have completed work on this documentation.

5.1.6 vsip_ccfftip_p - Perform FFT Operations (In-Place)

void vsip_ccfftip_f(const vsip_fft_f *fft, const vsip_cvview_f *y);

Description

These functions perform FFT (Fast Fourier Transform) operations using the specified FFT object in-place.

The performance for supported FFT sizes is standardized as $O(nlogn)$ . For sizes not directly supported by the FFT kernels a DFT fallback with a performance of $2 O(n )$ is standardized.

Parameters

const vsip_fft_p* fft: Pointer to the FFT object.
const vsip_cvview_p* y: Pointer to the complex input and output vector view.
