Gets real part of complex object values.

Declaration

Function RealPart(Vec: TMtxVec; VecIndex, Index, Len: integer): TMtxVec;

Description

Gets the real part of a Vec object complex elements [VecIndex]..[VecIndex+Len-1] and 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 Complex propety is false.

Declaration

Function RealPart(Vec: TMtxVec): TMtxVec;

      begin
        CreateIt(a,b);
        try
          a.SetIt(True,[1,2,3,4]); // = [1+2i, 3+4i]
          b.RealPart(a); // b = [1,3]
        finally
          FreeIt(a,b);
