`scipy.interpolate._dierckx:find_interval`

Summary

Find an interval such that t[interval] <= xval < t[interval+1].

Extended Summary

Uses a linear search with locality, see fitpack's splev.

Parameters

t : ndarray, shape (nt,): Knots
k : int: B-spline degree
xval : double: value to find the interval for
prev_l : int: interval where the previous value was located. if unknown, use any value < k to start the search.
extrapolate : int: whether to return the last or the first interval if xval is out of bounds.

Returns

interval : int: Suitable interval or -1 if xval was nan.
