outZeroCrossings | RealArray | X coordinates of the locations where the profile crosses the y=0 axis |
Description
The operation assumes linear interpolation between the profile values and finds precise locations at which the profile crosses the horizontal \(y = 0\) axis. For the constant profile sections of value 0 only the integer coordinates of the sampling points in the section are returned.
