Web14 Nov 2024 · The SciPy open source library provides the curve_fit () function for curve fitting via nonlinear least squares. The function takes the same input and output data as arguments, as well as the name of the mapping function to use. The mapping function must take examples of input data and some number of arguments. WebB-splines¶. A B-spline is an approximation of a continuous function over a finite- domain in terms of B-spline coefficients and knot points. If the knot- points are equally spaced with spacing \(\Delta x\), then the B-spline approximation to a 1-dimensional function is the finite-basis expansion.
