Polynomial Interpolation

It is implemented in JavaScript, using the jQuery and Prototype framewroks, and uses image formats like SVG and VML. Key features "JSXGraph": - Euclidean Geometry: Points, lines, circles, intersections, perpendicular lines, angles - Curve plotting: Graphs, parametric curves, polar curves, data...

Math::Polynomial::Solve is a Perl module to find the roots of polynomial equations. SYNOPSIS use Math::Complex; # The roots may be complex numbers. use Math::Polynomial::Solve qw(poly_roots); my @x = poly_roots(@coefficients); or use Math::Complex; # The roots may be complex numbers....

Linear Interpolation Calculator is a free solution that gives you the possibility to interpolate between values to arrive to the correct intermediate result. Linear interpolation has many uses usually in steam tables to find the unknown value.

Kriging and inverse distance are popular interpolation methods, especially in earth sciences. There are some routines already available on matlab but are severely limited by matlabs memory constraints. By using gstat to handle interpolation and variogram modelling, very large datasets are easily...

The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.Instead of putting all zero padding at the FFT *ends*, that padding can be split so that some are at the...

Sometimes it is important to be able to estimate the peak of a sampled continuous function between the samples. This is called subsample peak interpolation and is used in radar, delay estimation, and communication. Typically one fits a model to the sampled data and then finds the maximum of the...
