mdl_example

Automatic truncation of basis in least-squares curve fitting using a family of functions (1D). Given a set of basis functions Phi = {phi_0, phi_1, …, phi_m} (m < n, where n is the number of data points), this fitter will try the subsets {phi_0}, {phi_0, phi_1}, {phi_0, phi_1, phi_2, …, phi_{k-1}, phi_k}, …up to and including the original full set Phi, performing a least squares fit to the data for each subset. more…

freya

FREYA (Finite element based Radically ElementarY Applied mathematics library) is a Python library for numerical solution of partial differential equations (PDEs) by the finite element method (FEM), in one and two space dimensions, with C0 or C1 continuity across element interfaces. Given an element type, it discretizes weak forms automatically. more…
