Symbolic

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...

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...

This function takes two integer valued arguments and returns 1 if they are equal and 0 otherwise. The computation is done symbolically so the result is not actually returned as a number but as a symbolic expression for substituting symbolic values if required.$$f(a,b) := 1_{a = b},mbox{ for } a,b...
