FFTW is a free collection of fast C routines for computing the
Discrete Fourier Transform in one or more dimensions. It includes
complex, real, and parallel transforms, and can handle arbitrary
array sizes efficiently. FFTW is typically faster than other
publically-available FFT implementations, and is even competitive
with vendor-tuned libraries. (See our web page for extensive
benchmarks.) To achieve this performance, FFTW uses novel code-generation
and runtime self-optimization techniques (along with many other
tricks).

* Now respects CFLAGS/CPPFLAGS, no need for patches.
* autoconf removed, CONFIGURE_STYLE set to simple.
* Use do-install target now that the install method is so messy.
* New homepage.

HOMEPAGE is there for a reason.
Only bsd.port.mk uses tabspaces set to 4.
pre-package does not run as root, post-install does.
copying files is not good enough to make them executable.
and numerical analysis, very similar to Matlab.
Yorick's array syntax, interpreted programs are compact,
nearly free of explicit loops, and can run at speeds up to
20% of optimized compiled speed.
It can do interactive graphics via the X Window System,
including x-y plots, quadrilateral meshes and cell arrays.
Includes tools to assist making animated and simple 3d
graphs.
Supports output directly to your screen, in PostScript and
binary CGM format.

like a financial spreadsheet. When invoked it presents you
with a table organized as rows and columns of cells. If
invoked without a file argument, by default the initial
table is empty.
Each cell can be associated with a numeric value, a label
string and/or an expression which evaluates to a numeric
value or label string, often based on other cell values
(formula).

Math::GMP is designed to be a drop-in replacement both for Math::BigInt
and for regular integer arithmetic. Unlike BigInt, though, Math::GMP
uses the GNU gmp library for all of its calculations, as opposed
to straight Perl functions. This results in a speed increase of
anywhere from 5 to 30 times.
A Math::GMP object can be used just as a normal numeric scalar would
be -- the module overloads the normal arithmetic operators to provide
as seamless an interface as possible.
