clMatrix.PhaseSpectrum Method (TOpenCLMtxVec)

The phase angles (spectrum) of object elements.

Pascal

function PhaseSpectrum(const Vec: TOpenCLMtxVec): TOpenCLMtxVec; overload;

Calculates the phase angles (spectrum) of all Vec object elements. Phase values are returned in radians and are in the range -PI,PI. Size and Complex properties of the calling object are set implicitly to match Vec object. The phase angles are calculated from the following equation:

Example

var a,b: clMatrix; begin a.CopyCplxFromArray(1,2,TSingleArray.Create(1,2,3,-4)); // a = [1 + 2i, 3 - 4i] b.PhaseSpectrum(a); // b = [arctan2(1,2), arctan2(3,-4)]; end;
