Hi,
Does anyone know a good way to mathematically define/identify the onset of a plateau for a curve y = f(x) in a 2D plane?
A bit more background: I have a set of curves from which I'd like to extract the x values where the "plateau" starts, by applying a consistent definition of plateau onset.
Thanks,
Yifan
Hi!
I would propose to look for points where the derivative is close to zero.
You can identify values of x where the absolute value of the derivative is less than a small threshold value ε (this should have a small value like 1e-5 so that you can capture values near to zero).
The plateau onset can be determined by finding the minimum and maximum x-values where the derivative is close to zero. This will give you the range of x-values where the plateau starts.
