<p>Rating: 5 stars</p><p>Math::Algebra::Symbols is a (to me) new way to deal with symbolic math in Perl. I did myself spend a considerable amount of time thinking about the subject (the result of which is represented by the Math::Symbolic module) and really liked the more transparent interface of Math::Algebra::Symbols. However, I think it may become limited by the number of overloadable operators and contexts in the future and increasingly convolute the callers namespace.
<br><br>Since the two aforementioned modules cover much of the same ground, it's probably a good idea to compare them. Math::Symbolic is a much more abstracted attempt at a computer algebra system and thus has a much steeper learning curve. To get started with Philip's module, all you need to know is how to construct a Math::Algebra::Symbols object and most of the rest is done by the overloaded interface. The preferred method of constructing a Math::Symbolic tree/expression is, in contrast, to use its parser. Since Math::Symbolic tries to adhere to object-orientedness as much as possible, Math::Algebra::Symbols is faster for symbolic transformations, but lacks an option to translate a symbolic expression to a fast Perl subroutine or even inlined C for doing many evaluations of the algebraically transformed expression with different variable bindings as required by, for example, a function plotter. Since its normal use is much closer to ordinary calculations in Perl, Math::Algebra::Symbols is also better at cooperating with other mathematical modules like Math::Complex or Math::BigInt. (It's possible to use those modules in conjunction with Math::Symbolic, but more complicated. Please refer to the distribution's examples.)
<br><br>I really like Math::Algebra::Symbols and will try to work with the author for the benefit of both symbolic math packages.</p>Steffen MÃ¼ller2004-03-14T07:45:45
