Fast curve fitting
Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that … See more Most commonly, one fits a function of the form y=f(x). Fitting lines and polynomial functions to data points The first degree polynomial equation See more If a function of the form $${\displaystyle y=f(x)}$$ cannot be postulated, one can still try to fit a plane curve. Other types of curves, such as conic sections (circular, elliptical, parabolic, and hyperbolic arcs) or trigonometric functions (such as sine and … See more • Calibration curve • Curve-fitting compaction • Estimation theory • Function approximation See more Note that while this discussion was in terms of 2D curves, much of this logic also extends to 3D surfaces, each patch of which is defined by a net of curves in two parametric … See more Many statistical packages such as R and numerical software such as the gnuplot, GNU Scientific Library, MLAB, Maple, MATLAB, TK Solver 6.0, Scilab, Mathematica See more • N.
