This is an open-source MATLAB software package associated with the book Finite Elements and Fast Iterative Solvers with applications in incompressible fluid dynamics by Howard C. Elman, David J. Silvester, and Andrew J. Wathen, published by Oxford University Press.
The Matrix Computation Toolbox is a collection of MATLAB M-files containing functions for constructing test matrices, computing matrix factorizations, visualizing matrices, and carrying out direct search optimization. Various other miscellaneous functions are also included.
The Matrix Function Toolbox is a MATLAB toolbox connected with functions of matrices. It is associated with the book Functions of Matrices: Theory and Computation and contains implementations of of many of the algorithms described in the book.
This MATLAB Toolbox provides a collection of nonlinear eigenvalue problems. It contains problems from models of real-life applications as well as problems constructed specifically to have particular properties.
A Fortran 77 for delay differential equations.
In addition, see Jack Dongarra's project page for details of the many software packages (including LAPACK, ScaLAPACK, BLAS, Atlas, MPI, PVM, ...) he has developed and the software projects that he is involved in.
