XYFind

XYFind finds in a 1D or 2D dataset a datapoint for a given x-coordinate.

rvInfo = XYFind(hData, rsX, bInterpol)

Return Value

rvInfo is a vector with 3 elements or 0 if no point was found.

Value	Meaning
rvInfo[1]	Index of the found data point, starting with 1
rvInfo[2]	x-coordinate of the found data point
rvInfo[3]	y-coordinate of the found data point

Parameters

hData

The handle of a dataset created with XYCreate or TYCreate.

rsX

rsX x-coordinate of the data point.

bInterpol

If bInterpol is TRUE (1), the function returns for the given x-coordinate a linear interpolated y-coordinate and the index of the data point which is closest to the given x-coordinate. If bInterpol is FALSE (0) (default value), the function returns an x-/y-coordinate and the index of the data point which is closest to the given x-coordinate.

Comment

The x data of the dataset must be of monotone increasing or decreasing order.
