TSparseMtx.RealPart Method

TMtxVec RealPart(TMtxVec Vec)

Gets real part of complex object values.

#NameTypeDescription
1VecTMtxVecsource TVec or TMtx

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

Remarks:

The method method gets the real part of a complex object Vec and stores the real results in the calling object. Size and Dew.Math.TMtxVec.Complex properties of the calling object are set implicitly to match Vec object. Vec Dew.Math.TMtxVec.Complex property must be true otherwise an exception is raised.

Examples
Matrix a;
Matrix b;
a.SetIt(true,new double[] {1,2,3,4}); // = [1+2i, 3+4i]
b.RealPart(a); // b = new double[] {1,3}

Indexed: TMtxVec RealPart(TMtxVec Vec, Int32 VecIndex, Int32 Index, Int32 Len)

Gets the real part of a Vec object complex elements [VecIndex]..[VecIndex+Len-1].

#NameTypeDescription

2VecIndexInt32
3IndexInt32start index
4LenInt32element count

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

Remarks:

Stores the results in calling object real elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun or underrun or if Vec object Dew.Math.TMtxVec.Complex propety is false.
