sofm_icomplex32_to_polar()

void sofm_icomplex32_to_polar	(	struct icomplex32 *	complex,
		struct ipolar32 *	polar )

sofm_icomplex32_to_polar() - Convert (re, im) complex number to polar.

Parameters

complex	Pointer to input complex number in Q1.31 format.
polar	Pointer to output complex number in Q2.30 format for magnitude and Q3.29 for phase angle.

The function can be used to convert data in-place with same address for input and output. It can be useful to save scratch memory.

sofm_ipolar32_to_complex()

void sofm_ipolar32_to_complex	(	struct ipolar32 *	polar,
		struct icomplex32 *	complex )

sofm_ipolar32_to_complex() - Convert complex number from polar to normal (re, im) format.

Parameters

polar	Pointer to input complex number in polar format.
complex	Pointer to output complex number in normal format in Q1.31.

This function can be used to convert data in-place with same address for input and output. It can be useful to save scratch memory.
