The MathWorks - C/C++ Math Library  
The C/C++Math Library is a component of the MATLAB Compiler. The MATLAB Compiler includes the Compiler, the Math Library and the Graphics Library. The Math library provides the core math and data analysis routines from MATLAB in object library form. You can use the Math library with the MATLAB Compiler to create math functions based on MATLAB in your external applications. Or you can embed the Math library in standalone applications.

C++ Matrix Library  
This C++ library is intended for scientists and engineers who need to manipulate a variety of types of matrices using standard matrix operations. Emphasis is on the kind of operations needed in statistical calculations such as least squares, linear equation solve and eigenvalues. It supports the following matrix types: Matrix (rectangular matrix); UpperTriangularMatrix; LowerTriangularMatrix; DiagonalMatrix; SymmetricMatrix; BandMatrix; UpperBandMatrix; LowerBandMatrix; SymmetricBandMatrix; RowVector; ColumnVector.

Free code  
Here are bits of code and even a few complete programs you might find useful. Of course, I'd like to hear of any errors you find or corrections or improvements you make. C++ Section: The code here makes up a library of routines that I use frequently. None of them are as good as libraries provided by other sources but they are free, they seem to work with any ANSI C++ compiler, and they seem to work well with each other.

exmat - The Expression Template Matrix Library  
This is a generic, multi-platform C++ matrix library. It use expression template and meta-programming to provide specialized code for matrix operations. The specialized code can be as efficient as hand optimized code, and this process is transparent to the user. Therefore user can perform matrix operations in a most natural way e.g. A=B*C+D, but need not to worry about efficiency. The specialization will base on the size and the shape of the matrix. For small and static sized matrix, techniques like full unrolling and lazy evaluation will be applied. For big matrix that cannot fit into the cache, the library will act as a wrapper over other highly optimized library like BLAS.

This matrix template class can be used to perform common matrix operations in your C++ program like any other built-in data types. Though this class was written in compliance with ANSI/ISO C++ standard, you may encounter some compilation problem, particularly with older version of compilers, because all standard features of namespace, exception and template may not be fully supported in your compiler. In that case you may just want to disable any or all the above features by defining the appropriate macros.

A C++ library for manipulating algebraically defined points and curves in the plain. It represents points and curves exactly and makes use of several techniques for increasing the efficiency of manipulating the points. MAPC provides classes for representing and manipulating: multivariate polynomials with floating piont, multiprecision integer, or multiprecision rational coefficients; algebraic numbers represented as the roots of polynomials within an interval; 1- or 2-D points whose coordinates are defined as either algebraic or rational numbers; sections of algebraic plane curves; and 1- and 2-D boxes. Algorithms are implemented which provide functions for: rapidly finding the sign of a determinant of arbitrary size with entries that are arbitrary sized integers; isolating all intersections of two algebraic plane curves in a region; and decomposing a plane algebraic curve into monotonic subsections.

GiNaC is Not a CAS  
The name GiNaC is an iterated and recursive abbreviation for GiNaC is Not a CAS, where CAS stands for Computer Algebra System. It has been developed to become a replacement engine for xloops which is up to now powered by the Maple CAS. Its design is revolutionary in a sense that contrary to other CAS it does not try to provide extensive algebraic capabilities and a simple programming language but instead accepts a given language (C++) and extends it by a set of algebraic capabilities.
