A.J. Melhus, 4-18-10 Four more places to get help when you are using MATLAB:

## MATLAB's help function

% 1. Use the <help> command. %This brings up a basic list of features about the function or script % you are interested in, in the command window: help cosh % brings up a list of features of the cosh function

COSH Hyperbolic cosine. COSH(X) is the hyperbolic cosine of the elements of X. See also <a href="matlab:help acosh">acosh</a>. Overloaded functions or methods (ones with the same name in other directories) <a href="matlab:help sym/cosh.m">help sym/cosh.m</a> Reference page in Help browser <a href="matlab:doc cosh">doc cosh</a>

% 2. Use the HELP window. % Click on the characteristic blue box to bring up Matlabs help and demo % window. % - search for terms % - generally produces more results than <help> command line % - most sections have demos (view syntax and setup for problems)

## MATLAB on the internet

% 3. Use the internet. % - be wary of this method % - but it is sometimes best tool for quick, bare-bones info % - Google any Matlab-related question - someone probably has webpage % about it

## Ask an actual person

% 4. If you are on the Univ. of MD campus: % - Matlab tutors in Regents Drive Garage (PG-2) WAM lab % - tutors are pros and can help with most Matlab problems, if you know how % to ask % link: http://www.math.umd.edu/undergraduate/resources/tutoringmatlab.html % (you can also ask the OIT HelpDesk in CSS building about Matlab tutors)
