TVecInt.Ramp Method

Overload List

#	Signature	Description
1	function Ramp: TVecInt;	Fills the calling vector with a series following linear rule.
2	function Ramp(Offset: Double; Step: Double): TVecInt;	Fills the calling vector.
	└ indexed: function Ramp(Offset: Double; Step: Double; Index: Integer; Len: Integer): TMtxVecInt;

Overload 1: function Ramp: TVecInt;

Fills the calling vector with a series following linear rule.

Result: stored in self (calling object), returns self for chaining

Remarks:

Fills the calling vector with a series following the rule:

Values[k] :=  k

(Offset is zero and Step is one).

Examples

var a: TVecInt;
begin
    CreateIt(a);
    try
        a.Size(5,prInt32);
        a.Ramp(0,2); // [0, 2, 4, 6, 8]
    finally
        FreeIt(a);
    end;
end;

CreateIt(a);
try
    a.Size(5,prInt32);
    for i:= 0 to a.Length-1 do a[i] := i*2;
finally
    FreeIt(a);
end;

Overload 2: function Ramp(Offset: Double; Step: Double): TVecInt;

Fills the calling vector.

#	Name	Type	Description
1	Offset	Double	scalar
2	Step	Double	scalar

Result: stored in self (calling object), returns self for chaining

Remarks:

Method uses the following rule:

Values[k] := Offset + k*Step.

Examples

Values[k] :=  k

Indexed: function Ramp(Offset: Double; Step: Double; Index: Integer; Len: Integer): TMtxVecInt;

Fills the calling vector elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Offset	Double	scalar
2	Step	Double	scalar
3	Index	Integer	start index
4	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Method uses the following rule:

Values[k] := Offset + k*Step.

An exception is raised if calling vector array borders are overrun.

Examples

Values[k] := Offset + k*Step.
