MatrixInt.Reverse Method (TMtxVecInt, integer, integer, integer)

Reverse vector elements.

Pascal

function Reverse(const Vec: TMtxVecInt; const VecIndex: integer; const Index: integer; const Len: integer): TMtxVecInt; overload;

Description

The method reverses Vec vector elements from [VecIndex].. [VecIndex+Len-1] and stores them in the calling vector from [Index]...[Index+Len-1] by using the following equation:

This overload reverses calling vector elements in-place.
