SymPy is a Python library for symbolic mathematics.
It aims to become a full-featured computer algebra
system (CAS) while keeping the code as simple as
possible in order to be comprehensible and easily
extensible. SymPy is written entirely in Python and
does not require any external libraries.

Gmm++ is a generic C++ template library for sparse, dense and skyline
matrices. It is built as a set of generic algorithms (mult, add,
copy, sub-matrices, dense and sparse solvers ...) for any interfaced
vector type or matrix type. It can be view as a glue library allowing
cooperation between several vector and matrix types. However, basic
sparse, dense and skyline matrix/vector types are built in Gmm++,
hence it can be used as a standalone linear algebra library.
Interfacing a vector or matrix type means writing "traits" objects
called "linalg_traits", which describe their properties. The library
offers predefined dense, sparse and skyline matrix types.

MathDOM is a set of Python  modules (using PyXML or

as a Content MathML DOM. It currently parses MathML
and literal infix terms into a DOM document and writes

terms. The DOM elements are enhanced by domain specific
methods that make using the DOM a little easier.
Implementations based on PyXML and lxml/libxml2 are

Move misc/gretl to math/gretl; add secondary category of finance

        gretl is used in the mathematical analysis of time series,
        and has a functionality that is similar to various statistical
        and signal processing components of it++, octave, scilab,
        R, numpy/scipy, etc. -- most of which are in the math
        category.  It should really be placed there, rather than
        in misc.  In recognition of the fact that it implements
        some methods that are commonly (but not exclusively!) used
        in econometrics, it should also be given a secondary listing
        in finance.  (In my opinion, however, it shouldn't be given
        a primary listing in that category, because most of the
        ports there deal with the nuts-and-bolts of accounting,
        payment methods, taxes, and stock tracking.  To my knowledge,
        the only ports now in finance that remotely resemble gretl
        are quantlib, xtrader, and qtstalker, all of which employ
        simpler methods that are more specific to financial time
        series than are the more general methods in gretl.

That is, it estimates the c coefficients for a line-fit of the type

given a data set of N observations, each with k independent x variables
and one y variable. Naturally, N must be greater than k---and preferably
considerably greater. Any reasonable undergraduate statistics book will
explain what a regression is. Most of the time, the user will provide a
constant ('1') as x(0) for each observation in order to allow the
regression package to fit an intercept.

MathArray is a general library of classes for performing mathematical
operations on arrays (vectors, matrices, etc) of values. It can
operate on any standard 'C' number type plus numbers of complex
type. MathArray is implemented using a "class cluster" concept,
allowing one to perform mathematical calculations on a number without
necessarily being aware of what type (class) of number is being
operated on.  MathArray knows implicitly what types of operations can
be performed on what types of numbers and will automatically cast
itself to the correct number type representation to handle the
specific operation. Standard operations include addition, scalar and
matrix multiplication and logical operations. Mathematical operations
in the standard C math library are also supported, as well as
user-defined functions.
MathArray also does much more.  Arrays can be manipulated, transposed
and concatenated. One can extract subarrays or include subarrays within
larger arrays.

and can also be used to replace numarray.

Note:   Development for Numeric has ceased, and users should transisition to
