LFMats goal is to furnish convenient matrix tools for the finite element methods. Actually, theres a lot of libraries for linear algebra on the net, but it seems that its still hard to find flexible and high performance free software for the required procedures (genericity, speed, adaptated...

The Euler Mathematical Toolbox is a software written and maintained by R. Grothmann, associate professor of mathematics at the University of Eichstatt. Euler can also produce graphics and save the graphics in various formats, among them PNG and SVG. Graphics can also be imported into the text... Platforms: Windows

This function provides a supplement to the Matlab Symbolic toolbox to substitute and simplify long expressions. Maple does not provide this functionality.input-- Input expression that has some terms to be substituted. >> input='a^2-2b+c-3'; >> inputmode=1;Note that 'inputmode=1' indicates that...

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... Platforms: *nix

Math::Symbolic::MiscAlgebra contains miscellaneous algebra routines like det(). SYNOPSIS use Math::Symbolic qw/:all/; use Math::Symbolic::MiscAlgebra qw/:all/; # not loaded by Math::Symbolic @matrix = ([x*y, z*x, y*z],[x, z, z],[x, x, y]); $det = det @matrix; @vector = (x, y, z);...

For a symbolic input function f, returns the symbolic Hessian matrix. A real time saver imho I don't know how useful anyone will find this, but eh, my professor made us do it on the test, so I figure this will save at least someone the headache of having to find the Hessian by hand (provided they... Platforms: Matlab

Maple is a great tool for symbolic manipulation and is also very smart at plotting expressions, handling discontinuities,etc.However the plot customization and export possibilities are very primitive. Also, often I want to superimpose Maple plots with other data. This is very clumsy to handle in... Platforms: Matlab

Pymbolic is a small symbolic manipulation library. Two things set it apart from other libraries of its kind: * Users can easily write their own symbolic operations, simply by deriving from the builtin visitor classes. * Users can easily add their own symbolic entities to do calculations with....

Math::Symbolic::Constant is a Perl module that offers constants in symbolic calculations. SYNOPSIS use Math::Symbolic::Constant; my $const = Math::Symbolic::Constant->new(25); my $zero = Math::Symbolic::Constant->zero(); my $one = Math::Symbolic::Constant->one(); my $euler =... Platforms: *nix

Math::Symbolic::Variable is a Perl module which implements variables in symbolic calculations. SYNOPSIS use Math::Symbolic::Variable; my $var1 = Math::Symbolic::Variable->new('name'); $var1->value(5); my $var2 = Math::Symbolic::Variable->new('x', 2); my $var3 =... Platforms: *nix

Basically an equation editor, however not focused over one single equation, but you can write your mathematical artwork over several pages. You can easily move and copy your equations and expressions by mouse touch. Illustrate your equations using hand-drawing tools. Use symbolic calculator and... Platforms: Windows
