Web1-D smoothing spline fit to a given set of data points. Fits a spline y = spl (x) of degree k to the provided x, y data. s specifies the number of knots by specifying a smoothing condition. Parameters: x(N,) array_like 1-D array of independent input data. Must be increasing; must be strictly increasing if s is 0. y(N,) array_like

GNU spline is a program for interpolating between the data points in one or more datasets. Each dataset would consist of values for an independent variable and a dependent variable, which may be a vector of specified fixed length. When discussing interpolation, we call these variables `t' and `y', respectively.

WebA basis spline, or B-spline, is a piecewise polynomial function with specific properties that determine the polynomial degree/order. The idea behind using a B-spline curve is to determine a unique polynomial representation of a set of data, whether that data be structural points in 3D space or a set of data on a graph.
