Matlab Help:

• Matlab Helpdesk provides a search engine for commands and topics.
• To find instructions on how to use a particular command, type "help command_name".
• If you are looking for the name for a Matlab command, make a guess and type "lookfor guess".  If this doesnt work, type "help" to look for likely subtopics, then type "help subtopic".
