ACT: Matlab front-end for the Acoustic Toolbox written by Alec Duncan from the Centre for Marine Science and Technology at Curtin University.
atWinPII_f95. This is the latest and greatest version. The 'WinPII' in the name signifies that I have also pre-compiled it for a Windows, Pentium II machine. The executables in at\bin should work under Windows (various versions) on Pentium II machines. They don't seem to work under Linux. If you're using another machine or operating systems you'll need to recompile it which requires a Fortran95 compiler. (Fortran 90 and 95 are almost identical so you should be able to get it to work under f90.) The Makefiles are in a sort of Unix style. If you download cygwin (publicly available on the web) you get a sort of pseudo-Unix window in which you can just type 'make all' and 'make install' to recompile and install.
atLinuxPII_f95. Same as above but with binaries compiled under Linux.
BellhopRD This is a version modified by Giancarlo Dreini (formerly of SACLANTCEN) to allow for range-dependence in the sound speed profile. If you really need that feature this is the only currently available version, however, it is not current with atpII_f95 and it is sparsely commented.
at_Unix.tar.Z. This is an old Unix f77 version. It's made available here primarily since it has a set of cshell scripts for running the code under Unix.
atpII_f77old. This is an old PC f77 version, provided for those that do not have access to a Fortran90/95 compiler. However, there are many improvements in the f95 version.
atvaxold. This is an old VAX version going back to about 1991. Compilation and run scripts may be useful to anyone still using VAX computers, otherwise not recommended.
