The only requirement is to have
Matlab
installed. Any Matlab version from 6.5 (2005) will do. This is a commercial
product. Student versions can be bought for lower prices, as well as
Academic licenses (e.g. for Universities).
In principle, the pre-compiled MeX files are shipped with the package (for e.g.
looktxt), so that the software is ready to run. However, in the event of a re-compilation of MeX files, a
C compiler is often shipped with
Matlab (and installed automatically). The
iFit/
iFiles library may use it
sporadically.
