A complex exponential e^(j*W).

Class
TMtxVec

Calculate the calling object complex exponential in-place. An exception is raised if calling object is complex. If object is complex, you should use the Exp method instead.

Example 1

      var a: TVec;
      begin
        CreateIt(a);
        try
          a.SetIt(False,[1,2,3,4]);
          a.Expj;   // a = [e^i, e^2i, e^3i, e^4i]
        finally
          FreeIt(a);
        end;
      end;

Declaration

Function Expj(Omega: TMtxVec; OmegaIndex, Index, Len: integer): TMtxVec;

Description

Calculate the complex exponential for Omega elements [OmegaIndex]..[OmegaIndex+Len-1] and store the results in calling object elemets [Index]..[Index+Len-1]. Size and Complex properties of the calling vector must be set explicitly. An exception is raised if ConditionCheck is True and array borders are overrun or underrun.

---

Calculate the e^(j*W), a complex exponential. Omega must be a real object. If omega is complex, then use the Exp method.
