Matrix.PolarToCart Method

Overload List

#	Signature	Description
1	function PolarToCart(AmpltVec: TMtxVec; PhaseVec: TMtxVec): TMtxVec;	Converts the polar magnitude/phase pairs to cartesian pairs.
2	function PolarToCart(AmpltVec: TMtxVec; PhaseVec: TMtxVec; AIndex: Integer; PIndex: Integer; Index: Integer; Len: Integer): TMtxVec;	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: function PolarToCart(AmpltVec: TMtxVec; PhaseVec: TMtxVec): TMtxVec;

Converts the polar magnitude/phase pairs to cartesian pairs.

#	Name	Type	Description
1	AmpltVec	TMtxVec	source TVec or TMtx
2	PhaseVec	TMtxVec	source TVec or TMtx

Result: stored in self (calling object), returns self for chaining

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 Matrix.Complex properties of the calling object are set implicitly to match AmpltVec and PhaseVec objects.

Examples

var a,b,c: Matrix;
begin
    a.SetIt(1,4,false,[1,2,3,4]);  // a = [1,2,3, 4] //magnitude
    b.SetIt(1,4,false,[1,0,1,-1]); // b = [1,0,1,-1] /phase
    c.PolarToCart(a,b); // result stored in c = projections to Re and Im axis
end;

Overload 2: function PolarToCart(AmpltVec: TMtxVec; PhaseVec: TMtxVec; AIndex: Integer; PIndex: Integer; Index: Integer; Len: Integer): TMtxVec;

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

#	Name	Type	Description
1	AmpltVec	TMtxVec	source TVec or TMtx
2	PhaseVec	TMtxVec	source TVec or TMtx
3	AIndex	Integer	start index
4	PIndex	Integer
5	Index	Integer	start index
6	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

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