TVec.Resize Methods

Summary

Resizes vector size while preserving values.

Class
TVec

Declaration

Function Resize(Len: integer; ZeroIt: boolean = False): TMtxVec;

Description

Resizes calling vector Length to Len. If Length is less than Len and ZeroIt parameter is true, the remaining calling vector values are set to zero.

Example 1

        var a: Tvec;
        begin
          CreateIt(a);
          try
            a.SetIt(false,[1,2,3]);
            a.Resize(7,True); // a= [1,2,3,0,0,0,0]
          finally
            FreeIt(a);
          end;
        end;

Declaration

Function Resize(Src: TMtxVec; Len: integer; ZeroIt: boolean = False): TVec;

Description

Resizes calling vector Length to Len and fills it with Src vector first Len values. If Src length is less than Len and ZeroIt parameter is true, the remaining calling vector values are set to zero.

Example 1

        var a, b: Tvec;
        begin
          CreateIt(a,b);
          try
            a.SetIt(false,[1,2,3]);
            b.SetIt(false,[9]);
            b.Resize(a,7,True); // b=(9,1,2,3,4,0,0,0)
          finally
            FreeIt(a,b);
          end;
        end;
