Jacobi

Ever wonder how the weights and abscissae are calculated for the numerical conversion from radiance to flux? The long and the short of it is that Gauss-Jacobi quadrature determines the weights and abscissae which is similar to Gaussian for low-point quadrature but differs substantially for...

Implementation based on:"Finite-Element Discretization Of Static Hamilton-Jacobi Equations Based On A Local Variational Principle"by F. Bornemann and C. RaschComments:1. There is no restriction on the type of triangulation, i.e. it does not need to be acute. But the method will require more than... Platforms: Matlab

Math::Symbolic is a Perl module for symbolic calculations. SYNOPSIS use Math::Symbolic; my $tree = Math::Symbolic->parse_from_string(1/2 * m * v^2); # Now do symbolic calculations with $tree. # ... like deriving it... my ($sub) = Math::Symbolic::Compiler->compile_to_sub($tree); my...

mpmath is a replacement for Python's float/complex types and math/cmath modules with unlimited precision and exponent sizes. The mpmath software is written entirely in Python without any external dependencies and hence runs almost anywhere, without the need for compilation. To install, unpack... Platforms: Mac
