TVec::PolarToCart Method

TVec Class

Overload List

#SignatureDescription
1TMtxVec *PolarToCart(TMtxVec *AmpltVec, TMtxVec *PhaseVec);Converts the polar magnitude/phase pairs to cartesian pairs.
2TMtxVec *PolarToCart(TMtxVec *AmpltVec, TMtxVec *PhaseVec, int aIndex, int PIndex, int Index, int Len);Convert AmpltVec elements [aIndex]..[aIndex+Len-1] and PhaseVec elements [PIndex]..[PIndex+Len-1] from polar form (radius,angle) to cartesian form (x,y).

Overload 1: TMtxVec *PolarToCart(TMtxVec *AmpltVec, TMtxVec *PhaseVec);

Converts the polar magnitude/phase pairs to cartesian pairs.

#NameTypeDescription
1AmpltVecTMtxVec *
2PhaseVecTMtxVec *
Remarks:

Convert all AmpltVec and PhaseVec elements (combined) from polar to cartesian form. If AmpltVec and PhaseVec size is not the same , an exeption is raised. The results are stored as complex numbers (x=Re, y=Im) in the calling object. Size and TVec::Complex properties of the calling object are set implicitly to match AmpltVec and PhaseVec objects.

Examples
#include "MtxVec.h"
#include "Units.MtxVec.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxVec;

void Example()
{
    TVec *a, *b, *c;
    CreateIt(a, b, c);
    a->SetIt(false, DewArray<double>{1,2,3,4});  // a = [1,2,3, 4] //magnitude
    b->SetIt(false, DewArray<double>{1,0,1,-1}); // b = [1,0,1,-1] /phase
    c->PolarToCart(a,b); // result stored in c = projections to Re and Im axis
    FreeIt(a, b, c);
}

Overload 2: TMtxVec *PolarToCart(TMtxVec *AmpltVec, TMtxVec *PhaseVec, int aIndex, int PIndex, int Index, int Len);

Convert AmpltVec elements [aIndex]..[aIndex+Len-1] and PhaseVec elements [PIndex]..[PIndex+Len-1] from polar form (radius,angle) to cartesian form (x,y).

Remarks:

The results are stored as complex numbers (x=Re, y=Im) in the calling object elements [Index]..[Index+Len-1]. Size and TVec::Complex properties of the calling object must be set explicitly. An exception is raised if TVec::ConditionCheck is True and array borders are overrun/underrun.
