median
median (waveName [, x1, x2])
The median function returns the median value of the wave for points from x=x1 to x=x2 .
The median function was added in Igor Pro 7.00.
Details
If you omit x1 and x2, they default to -INF and +INF, respectively.
The X scaling of the wave is used only to locate the points nearest to x=x1 and x=x2. To use point indexing, replace x1 with "pnt2x(waveName,pointNumber1)", and a similar expression for x2.
If the points nearest to x1 or x2 are outside the point range of 0 to numpnts(waveName )-1, median limits them to the nearest of point 0 or point numpnts(waveName)-1.
If the wave contains NaNs they are skipped.
The function returns NaN if the input wave has zero non-NaN points.
