Hi Christopher, if you are interested in the 1d problem, you might also consider a spline fit of order 1, for example with scipy.interpolate, see [1]. Cheers Klaus [1] https://docs.scipy.org/doc/scipy/reference/tutorial/interpolate.html#spline-... On 03/06/2021 13:12, Mark Bakker wrote:

Do any of you know of code for finding an optimum linear piecewise fit to a set of points?
Somethin like what is described in this article:
https://www.hindawi.com/journals/mpe/2015/876862/ <https://www.hindawi.com/journals/mpe/2015/876862/>
At a glance, that looked just hard enough to code up that I'm hoping someone has already done it :-)
