TSparseMtx.PolarToCart Method

Overload List

#	Signature	Description
1	TMtxVec PolarToCart(TMtxVec AmpltVec, TMtxVec PhaseVec)	Converts the polar magnitude/phase pairs to cartesian pairs.
2	TMtxVec PolarToCart(TMtxVec AmpltVec, TMtxVec PhaseVec, Int32 aIndex, Int32 PIndex, Int32 Index, Int32 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.

#	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 Dew.Math.TMtxVec.Complex properties of the calling object are set implicitly to match AmpltVec and PhaseVec objects.

Examples

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

Overload 2: TMtxVec PolarToCart(TMtxVec AmpltVec, TMtxVec PhaseVec, Int32 aIndex, Int32 PIndex, Int32 Index, Int32 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).

#	Name	Type	Description
1	AmpltVec	TMtxVec	source TVec or TMtx
2	PhaseVec	TMtxVec	source TVec or TMtx
3	aIndex	Int32
4	PIndex	Int32
5	Index	Int32	start index
6	Len	Int32	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 Dew.Math.TMtxVec.Complex properties of the calling object must be set explicitly. An exception is raised if Dew.Math.TMtxVecBase.ConditionCheck is True and array borders are overrun/underrun.
