| Summary : Symbolic calculations
|
Description :
Math::Symbolic is intended to offer symbolic calculation capabilities to
the Perl programmer without using external (and commercial) libraries
and/or applications.
Unless, however, some interested and knowledgable developers turn up to
participate in the development, the library will be severely limited by my
experience in the area. Symbolic calculations are an active field of
research in CS.
There are several ways to construct Math::Symbolic trees. There are no
actual Math::Symbolic objects, but rather trees of objects of subclasses of
Math::Symbolic. The most general but unfortunately also the least intuitive
way of constructing trees is to use the constructors of the
Math::Symbolic::Operator, Math::Symbolic::Variable, and
Math::Symbolic::Constant classes to create (nested) objects of the
corresponding types.
Furthermore, you may use the overloaded interface to apply the standard
Perl operators (and functions, see OVERLOADED OPERATORS) to existing
Math::Symbolic trees and standard Perl expressions.
Possibly the most convenient way of constructing Math::Symbolic trees is
using the builtin parser to generate trees from expressions such as \'2 *
x^5\'. You may use the \'Math::Symbolic->parse_from_string()\' class method
for this.
Of course, you may combine the overloaded interface with the parser to
generate trees with Perl code such as \'$term * 5 * \'sin(omega*t+phi)\'\'
which will create a tree of the existing tree $term times 5 times the sine
of the vars omega times t plus phi.
There are several modules in the distribution that contain subroutines
related to calculus. These are not loaded by Math::Symbolic by default.
Furthermore, there are several extensions to Math::Symbolic available from
CPAN as separate distributions. Please refer to SEE ALSO for an incomplete
list of these.
For example, Math::Symbolic::MiscCalculus come with \'Math::Symbolic\' and
contains routines to compute Taylor Polynomials and the associated errors.
Routines related to vector calculus such as grad, div, rot, and Jacobi- and
Hesse matrices are available through the Math::Symbolic::VectorCalculus
module. This module is also able to compute Taylor Polynomials of functions
of two variables, directional derivatives, total differentials, and
Wronskian Determinants.
Some basic support for linear algebra can be found in
Math::Symbolic::MiscAlgebra. This includes a routine to compute the
determinant of a matrix of \'Math::Symbolic\' trees.
