TMtxVec.Cos Methods

Summary

Cosine.

Declaration

Function Cos(X: TMtxVec; XIndex: integer; Index: integer; Len: integer): TMtxVec;

Description

Calculate the cosine 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 calling object and the calling object must be set explicitly. An exception is raised if array borders are overrun.

Declaration

Function Cos: TMtxVec;

Description

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

Example 1

      var a: TVec;
      begin
        CreateIt(a);
        try
          a.SetIt(True,[1,-2,3,4]);
          a.Cos; // Computes complex sine
        finally
          FreeIt(a);
        end;
      end;

Declaration

Function Cos(X: TMtxVec): TMtxVec;

Description

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

Declaration

Function Cos(Index: integer; Len: integer): TMtxVec;

Description

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