TMtxVec.Cosh Methods

Summary

Hyperbolic cosine.

Declaration

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

Description

Calculate the hyperbolic cosine 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 Cosh: TMtxVec;

Description

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

Example 1

      var a: TVec;
      begin
        CreateIt(a);
        try
          a.SetIt(False,[1,1.5,2,0.3]);
          a.Cosh;
        finally
          FreeIt(a);
        end;
      end;

Declaration

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

Description

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

Declaration

Function Cosh(X: TMtxVec): TMtxVec;

Description

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