Log base 2.

Class
TMtxVec

Calculate the log base 2 for all X elements and store the results in the calling object. Size and Complex properties of the calling vector are set implicitly to match the X object.

Example 1

      var a: TVec;
      begin
        CreateIt(a);
        try
          a.SetIt(False,[1,2,4,8]);
          a.Log2;
        finally
          FreeIt(a);
        end;
      end;

Declaration

Function Log2(X: TMtxVec; XIndex, Index, Len: integer): TMtxVec;

Description

Calculate the log base 2 for X elements [XIndex]..[XIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1]. Size and Complex properties of the calling object must be set explicitly. An exception is raised if ConditionCheck is True and array borders are overrun.
