Syntax

[C/C++:]
void ggAddSquareWave(int npts, GPOINT *points, int pos, int xory);

[F90:]
subroutine ggAddSquareWave(npts, points, pos, xory)

integer, intent(in) :: npts, pos, xory
type(GPOINT), intent(in) :: points(*)

Arguments

npts
The number of points in the points array

points
Array of dimension npts, giving the X and Y axis values of the points that the square wave is fitted to

pos
Flag controlling the square wave interpolation. The value determines the position of the change in height from one point to the next

= GCURRENT

Change occurs at current point held in points.x and points.y

= GHALFWAY

Change occurs half way between current and next point

= GNEXT

Change occurs at next point

xory
The direction in which the square wave is fitted to the data set. The value of xory represents the axis to which the height change in the square wave is perpendicular to:

= GXAXIS

X axis

= GYAXIS

Y axis

Description

The routine ggAddSquareWave() takes the points held in the points array and fits a square wave to them. The square wave passes through all the given points. The changes in height can occur at one of three positions about the given points, depending on the value of pos.
