Thankfully, Matlab has extensive ``Help'' documentation that is built in and easy to access. Type ``help'' at the command prompt to see a list of all the help topics in Matlab. To read about any particular topic simply type ``help topic name '' at the command prompt. For example, if you want to get an idea of the audio support in Matlab, simply type
>> help audio
If you want any help on how to call a function, you simply type in ``help'' and the function name at the command prompt. For example
>> help sound >> help cos >> help plot >> help help
If you want to complete a certain task and you're wondering whether or not there's a built in Matlab function that will do it for you, you may be able to find what you're looking for using ``lookfor''. For example, what Matlab function could you use to make a sine wave?
>> lookfor sine
