MATLAB is exceptionally strong in linear algebra, numerical methods, and
graphical interpretation of data. It is easily programmed and relatively easy
to learn to use. As suchit has proven invaluable to engineers and scientists
whoareworkingonproblemsthatrelyonscientifictechniquesandmethodsat
which MATLAB excels. Very often the individuals and groups that so employ
MATLAB are primarily interested in the numbers and graphs that emerge
from MATLAB commands, processes, and programs. Therefore, it is enough
for them to work in a MATLAB Command Window, from which they can eas-
ily print or export their desired output. At most, the production technique
described in Chapter 3 involving diary files is sufficient for their presentation
needs.

presentation mode, which affords graphics integrated with text, with different
formats for input and output, and one that can communicate effortlessly with
other software applications. Some of MATLAB's competitors have focused on
suchneedsindesigningtheinterfaces(orfrontends)behindwhichtheirmath-

rather than the interface — and for the reasons and purposes outlined above,
that is clearly a wise decision. But for academic users (both faculty and espe-
cially students), for authors, and even for applied scientists who want to use
MATLAB to generate slick presentations, the interface demands can become
very important. For them, MATLAB has provided the
