Installation Guide for pc

Setting Your Initial Current Directory
By default, when you start MATLAB using the shortcut the installer puts on 
your desktop, the initial current directory is the 
$MATLAB\work
directory, where 
$MATLAB
represents the name of your installation directory. The \
work
directory is a good place to store the M-files you modify and create because the 
MATLAB uninstaller does not delete the \
work
directory if it contains files. 
You can, however, use any directory as your MATLAB initial current directory. 
To specify another directory as your initial current directory, right-click on the 
MATLAB shortcut that the installer creates on your desktop and select the 
Properties
option. Specify the name of the directory in the Start in field.

Setting Up MATLAB Environment Options
To include welcome messages, default definitions, or any MATLAB expressions 
that you want executed every time MATLAB is invoked, create a file named 
startup.m
in the 
$MATLAB\toolbox\local
directory. MATLAB executes this 
file each time it is invoked. 
Configuring Certain Release 12.1 Products
Certain Release 12.1 products require additional configuration. The following 
table lists these products and the commands used to configure them. If you 
installed any of these products, see the documentation for that product for 
detailed configuration information.
Excel Link Versions 
By default, Excel Link (a separately orderable product) supports Excel 97. 
However, the installer puts two versions of Excel Link in the 
toolbox\exlink
subdirectory. Files with 95 appended to their names (e.g. 
excllink95.xla
and 
ExliSamp95.xls
) correspond to Excel 7. Files without this identifier (e.g., 
excllink.xla
and 
ExliSamp.xls
) correspond to Excel 97. Use the appropriate 
files for your version of Excel.
