jscl-meditor is a Java symbolic computing library and math editor. It includes polynomial system solving, vectors and matrices, factorization, derivatives, integrals (rational functions), boolean algebra, simplification, MathML output, Java code generation, and geometric algebra.

The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.

MathLib is a PalmOS shared library which makes a complete set of IEEE-754 double-precision math functions available to other Palm applications. These functions include all the standard routines normally accessed by including "math.h" on other systems, including trigonometry (with inverse and hyperbolic), logarithms, exponentiation, and miscellaneous helper functions.
