Several numerical mathematical utilities. For example, utilities for solving the Quadratic, Cubic, and Quartic Equations; solving N Equations in N Unknowns; Eigenvalues and Eigenvectors; and more.
GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.
Here you can curve fit and surface fit your 2D and 3D data online with
a rich set of error histograms, error plots, curve plots, surface plots,
contour plots, VRML, auto-generated source code, and PDF file output.
If you're looking for quality curve fitting and surface fitting, this is the
site for you! Source code is available at the Google Code Repository.
To begin, select an equation family from the drop-down menus above or try
the "Function Finders" to help determine the best curve fit for your data.
180 years ago, famous mathematician Évariste Galois was killed in a duell. He was only 20 years old. And why? Just because of a girl. Her name was Stéphanie-Félicie Poterine du Motel, the daughter of a physician.
