Unit Class
Integer
PeakSlopeIndex
The PeakSlopeIndex function locates the region of peak slope of the X-Y curve.
Returns
This function returns the start or end index of the region of the peak slope of the X-Y curve.
Syntax
PeakSlopeIndex(markerNumber, y-axis, x-axis, segmentLength[, startIndex, endIndex, tolerance])
Parameters
MarkerNumber - 1 returns the start index; 2 returns the end index.
y-axis - The Y-Axis array data.
x-axis - The X-Axis array data.
SegmentLength - The percentage of the peak Y-Axis used to determine the regions used in the slope
calculations.
StartIndex - The optional start index of the region. If this parameter is missing, the start is associated with
the first data point in the array.
