Description:
Math::Symbolic is intended to offer symbolic calculation capabilities
to the Perl programmer without using external (and commercial)
libraries and/or applications.
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) 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.
