TVec.Ramp Methods

Summary

Fills the calling vector with a series following linear rule.

Class
TVec

Declaration

Function Ramp(Offset, Step: TCplx; Index, Len: integer): TVec;

Description

Fills the calling vector elements [Index]..[Index+Len-1] with a series following the rule:

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

If the calling vector is complex, only the real part is set. An exception is raised if array borders of the calling vector are overrun.

Declaration

Function Ramp(Offset, Step: TSample; Index, Len: integer): TVec;

Description

Fills the calling vector elements [Index]..[Index+Len-1] with a series following the rule:

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

If the calling vector is complex, only the real part is set. An exception is raised if calling vector array borders are overrun.

Declaration

Function Ramp(Offset: TCplx; Step: TSample; Index, Len: integer): TVec;

Description

Fills the calling vector elements [Index]..[Index+Len-1] with a series following the rule:

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

The Offset is complex, but the step is real.

Declaration

Function Ramp(Offset: TCplx; Step: TSample): TVec;

Description

The Offset is complex, but the step is real.

Declaration

Function Ramp: TVec;

Description

Fills the calling vector with a series following the rule:

Values[k] :=  k

(Offset is zero and Step is one). If the calling vector is complex, only the real part is set.

Example 1

        var a: TVec;
        begin
          CreateIt(a);
          try
            a.Size(5,True);
            a.Ramp(0,Pi);
            a.Sin;
          finally
            FreeIt(a);
          end;
        end;

which is identical to:

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

Declaration

Function Ramp(Offset, Step: TCplx): TVec;

Description

Fills the calling vector with a series following the rule:

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

Declaration

Function Ramp(Offset, Step: TSample): TVec;

Description

Fills the calling vector with a series following the rule:

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

If the calling vector is complex, only the real part is set.
