4.4.5 vsip_cvmag_p - Compute Magnitude of Complex Vector View

void vsip_cvmag_f(const vsip_cvview_f *a, const vsip_vview_f *r);

Description

This function computes the element-wise magnitude (absolute value) of each complex element in the vector view a and stores the result in the real vector view r. The magnitude of a complex number $a+ bi$ is calculated as $⎷-2---2 a + b$ .

Parameters

const vsip_cvview_p* a: Pointer to the source complex vector view.
const vsip_vview_p* r: Pointer to the destination real vector view where the magnitudes will be stored.

Example

vsip_cvview_f *complex_vector_view; 
vsip_vview_f *magnitude_vector_view; 
 
// Assuming complex_vector_view and magnitude_vector_view have been properly initialized 
vsip_cvmag_f(complex_vector_view, magnitude_vector_view);
