Inverse tangens.

Class
TMtxVec

Calculate the inverse tangens for all calling object elements in-place. The return values are expressed in radians.

Example 1

      var A,B: TMtx;
      begin
        CreateIt(A,B);
        A.SetIt(2,2,True,[1,0, 2,0
                          2,0  4,1]);  // 2x2, complex matrix
        B.ArcTan(A);                                              
        FreeIt(A,B);
      end;

Declaration

Function ArcTan(Index, Len: integer): TMtxVec;

Description

Calculate the inverse tangens of calling object elements [Index]...[Index+Len-1] in-place. An exception is raised if array borders are overrun.

Declaration

Function ArcTan(X: TMtxVec): TMtxVec;

Description

Calculate the inverse tangens of all X object elements and store the results in the calling object. Size and Complex properties of calling object are adjusted automatically.

---

Calculate the inverse tangens of X object elements [XIndex]...[XIndex+Len-1]. The results are stored in calling object elements [Index]...[Index+Len-1]. Size and Complex properties of the calling object must be set explicitly. An exception is raised if array borders are overrun.
