2.1.6 vsip_rect_p - Convert Polar to Cartesian Coordinates

vsip_cscalar_f vsip_rect_f(vsip_scalar_f radius, vsip_scalar_f theta); 
vsip_cscalar_d vsip_rect_d(vsip_scalar_d radius, vsip_scalar_d theta);

Description

This function converts polar coordinates (magnitude and phase angle) to a complex scalar in Cartesian coordinates (real and imaginary parts). The function computes the Cartesian coordinates from polar coordinates using Euler’s formula:

The phase angle should be provided in radians.

Parameters

• vsip_scalar_p radius: Magnitude (radius) of the complex number.

• vsip_scalar_p theta: Phase angle in radians.

Return Value

• Returns the complex scalar in Cartesian coordinates.
