Maxima is a descendant of DOE Macsyma, which had its origins in the
late 1960s at MIT. It is the only system based on that effort still
publicly available and with an active user community, thanks to its
open source nature. Macsyma was the first of a new breed of computer
algebra systems, leading the way for programs such as Maple and
Mathematica. Maxima itself is reasonably feature complete at this
stage, with abilities such as symbolic integration, 3D plotting, and
an ODE solver, but there is a lot of work yet to be done in terms of
bug fixing, cleanup, and documentation.

This module implements some algorithms for calculating Fast Fourier
Transforms for one-dimensional data sets of size 2^n. The data,
assumed to arise from a constant sampling rate, is represented by
an array reference, which is then used to create a Math::FFT object.
Available methods include complex and real discrete fourier transforms,
convolution, power spectra and windowing functions, as well as some
statistical utilities.
o put examples into ${PREFIX}/share/examples/xspread
o remove unnecessary build documentation from PLIST
o use ${MASTER_SITE_OPENBSD} since the original ftp server refuses
anonymous connections
o add comment about license
o regen patches with update-patches
Bit::Vector is an efficient C library which allows you to handle
bit vectors, sets (of integers), "big integer arithmetic" and
boolean matrices, all of arbitrary sizes.
Changes in this release:
Minimized and isolated constructs that do not adhere to C/C++
standards, and added flags NTL_CLEAN_INT and NTL_CLEAN_PTR
which force stricter compliance with these standards
Added functions IsWhiteSpace, CharToIntVal,
and IntValToChar to the tools module
Added methods allocated, position1 to generic vector classes
Added method allocated to the class vec_GF2
Added conversion routines from unsigned int/long to int, long, float,
and double
Added routines AddPrec, SubPrec, etc., to the RR
module, and declared the practice of directly assigning to the variable
RR::prec obsolete
Fixed a number of minor bugs.
