Where to find HELP on MATLAB
1. If you know the name of the function you want help on you can use
the matlab help command.
>> help % lists the names of all Directories in the
% MATLABPATH search path
>> help dir_name % lists contents of directory dir_name, if
% dir_name is a directory in the MATLABPATH
% and contains a Contents.m file
>> help fname % Shows the help message for a particular function
The command "more on" sets matlab to pause between screenfuls of
text, rather than scrolling it beyond view. (Use spacebar to
advance a page, RETURN to advance a line, "q" to exit from the
item being displayed.)
2. If you are unsure of the function name, you can try to find the
name using the Matlab "lookfor" command. This command does a
keyword search on the first comment line of each .m file in the
MATLABPATH, and may take some time to finish. (The switch "-all"
can be used to search through the entire first comment block, but
this will lengthen the search.) For example
>> lookfor cartesian
returns
CART2POL Transform Cartesian to polar coordinates.
CART2SPH Transform Cartesian to spherical coordinates.
POL2CART Transform polar to Cartesian coordinates.
SPH2CART Transform spherical to Cartesian coordinates.
3. The MathWorks' web-based "Help Desk" includes a full documentation
set in Adobe Acrobat (PDF) format, a searchable command index, and
links to other information. It can be started from matlab:
>> helpdesk
or from Athena
athena% add matlab; matlabdoc
and will open up in your web browser.
4. Help is available on matlab in OLH.
athena% help matlab
5. There is a "Matlab on Athena" document (AC-71) available on the web
at http://web.mit.edu/olh/Matlab/Matlab.html, or from CopyTech
(11-004). SIPB also puts out an "Inessential Matlab" document.
6. Matlab user guides and toolbox manuals are available in the
Consulting office (1st floor N42). Many can be checked out until
the end of the day in exchange for an MIT ID. Copies of some of
these manuals can be found in a few clusters around campus
(e.g. Barker and Hayden libraries).
7. Still can't find the answer to your question? Ask olc.
athena% olc ask
Topic: matlab
8. One additional source of information is the newsgroup comp.soft-sys.matlab.
This newsgroup often has technical discussions that include members of the
MathWorks staff and Matlab users.
