produced using GFortran. They use dynamic link libraries so

standard does not clarify whether record lengths are in bytes or
words. For some compilers, e.g. the Intel Fortran you need to use
a compiler switch making bytes the standard unit for record
lengths. We use the free gfortran compiler. The free g95 compiler
has also worked well in the past; however, I believe the current
version of AT uses Fortran features not implemented in g95.
compilation is done using standard Makefiles that work under Unix,
OS X, etc. We also use them under Windows with either the Cygwin
system or MinGW, which provide a Unix-like environment under
Windows. Cygwin and Mingw are also freely distributed.

We currently run the Acoustics
Toolbox through Matlab using shell-escape commands to execute the
binaries and a variety of Matlab scripts and functions (in
at/matlab) to manipulate and display the output. If you don't have
Matlab then you'll have to figure out your own graphics. In that
case, the Matlab plot routines at least provide a good example of
how to read the file formats.
The only challenge in this phase
is to get the paths set up properly. When you call the Acoustics
Toolbox through Matlab, you're using Matlab scripts. Those Matlab
scripts use the Matlab 'which' command to find the location of the
binaries within the Matlab search path. Therefore, Matlab has to
have its path set to include the Acoustics Toolbox.
Here's an example of running kraken at the regular command line
(rather than from inside Matlab):
The 'cd' command above is hypothetical. You should cd to the
directory where you've created the Acoustics Toolbox. If you get
an error, the likely problem is that the path is not set properly.
The following commands may be useful in tracking that down.
If instead, you run the package
through Matlb, start Matlab and make sure you have 'at' in your
path. Check that by typing to following on the Matlab command
If the above runs without error,
then go to at/tests and type 'runtests' to execute a huge battery
of test cases. If the above generates an error then it could be
you don't have at/Matlab in your Matlab path.
Incidentally, the test battery
that you run by typing 'runtests' may fail somewhere unless you
have a beefy computer--- it generates a very large number of
figures and consumes a lot of memory in the process. However, it's
easy enough to restart the test battery at exactly the point where
it overwhelms your system.
version of the Acoustics Toolbox
Note that at/Matlab includes
versions of BELLHOP, KRAKEL, SCOOTER, and SPARC in Matlab (Kraken
to come soon). The Matlab versions are typically much slower;
however, they're much easier to use and modify. The Matlab version
of SCOOTER has an optional Mex file (thanks to Paul Hursky) for
the inner loop which is a tridiagonal solver. If you compile the
Mex file, the Matlab SCOOTER runs about as fast as the Fortran
one. The Matlab versions are not maintained as carefully as the Fortran
versions and may not have the latest updates.
J. P. Ianniello also wrote a Matlab
version of Kraken, called Krak_mat. See the link on oalib on the 'Modes' page. It
implements the Kraken algorithm but is not set up to
use the same
input and output files.
