fosc.m is a Matlab GUI illustrating forced oscillations.

sake0.3.tgz is a Fortran 95 library that
generates specialpurpose, 4D quadrature rules used in
boundary element computations for integral equations on surfaces.

gaussquad2.5.tgz provides a Fortran 95
module that generates all of the classical Gauss quadrature rules,
including the Radau and Lobatto variants. The package includes test
programs and bindings for C and Python. (The latter require a fortran compiler,
such as g95, that supports a few of the interoperability features in the f2003
standard.)

libnpy0.5.tgz is a small library for writing
a C or Fortran array to a data file, using the NumPy binary format. A
Python script can easily load such a .npy file to create a NumPy array.

blocktstsolver0.1.tgz provides an FFT based solver
for block tridiagonal symmetric Toeplitz matrices.
