Successive parabolic interpolation is a technique for finding the extremum (minimum or maximum) of a continuous unimodal function by successively fitting parabolas (polynomials of degree two) to a function of one variable at three unique points or, in general, a function of n variables at … See more Only function values are used, and when this method converges to an extremum, it does so with an order of convergence of approximately 1.325. The superlinear rate of convergence is superior to that of other methods with only … See more Alternating the parabolic iterations with a more robust method (golden section search is a popular choice) to choose candidates can greatly increase the probability of convergence without hampering the convergence rate. See more On the other hand, convergence (even to a local extremum) is not guaranteed when using this method in isolation. For example, if the three points are collinear, the resulting parabola is degenerate and thus does not provide a new candidate point. Furthermore, … See more • Inverse quadratic interpolation is a related method that uses parabolas to find roots rather than extrema. • Simpson's rule uses parabolas to … See more lance blake architect
Optimization: Minimization by Parabolic Interpolation
WebAccuracy. If a C 0 function is insufficient, for example if the process that has produced the data points is known to be smoother than C 0, it is common to replace linear interpolation with spline interpolation or, in some cases, polynomial interpolation.. Multivariate. Linear interpolation as described here is for data points in one spatial dimension. For two … Webthe Gaussianwindow transform magnitude is precisely a parabola on a dBscale. As a result, quadratic spectral peak interpolation is exactunder the Gaussian window. Of course, we … WebMatlab for Parabolic Peak Interpolation Section §F.2lists Matlab/Octave code for finding quadratically interpolated peaks in the magnitude spectrumas discussed above.
