"In the mathematical subfield of numerical analysis, a B-spline or basis spline is a spline function that has minimal support with respect to a given degree, smoothness, and domain partition. Any spline function of given degree can be expressed as a linear combination of B-splines of that degree. Cardinal B-splines have knots that are equidistant from each other. B-splines can be used for curv… " - Splines maths

WebDefinition. A curve that is obtained by attaching a string which is imaginary and then winding and unwinding it tautly on the curve given is called involute in differential geometry. Involute or evolvent is the locus of the free end of this string. The evolute of an involute of a curve is referred to that original curve. WebCubic spline interpolation is the process of constructing a spline f: [x1, xn + 1] → R which consists of n polynomials of degree three, referred to as f1 to fn. A spline is a function defined by piecewise polynomials. Opposed to regression, the interpolation function traverses all n + 1 pre-defined points of a data set D.
