TMtxVec.Coth Methods

Summary

Hyperbolic cotangens.

Declaration

Function Coth(X: TMtxVec): TMtxVec;

Description

Calculate the hyperbolic cotangens for all X object elements and store the results in the calling object. Size and Complex properties of calling object are adjusted automatically.

Declaration

Function Coth(X: TMtxVec; XIndex, Index, Len: integer): TMtxVec;

Description

Calculate the hyperbolic cotangens for 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.

Declaration

Function Coth: TMtxVec;

Description

Calculate the hyperbolic cotangens of all caling object elements in-place.

        try
          a.SetIt(False,[1,1.5,2,0.3]);
          a.Coth;
        finally
          FreeIt(a);
        end;
      end;

Declaration

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

Description
