help classname.methodname displays help for the method, methodname, of the<br />

fully qualified class, classname. If you do not know the fully qualified class for<br />

the method, use class(obj), where methodname is of the same class as the<br />

object obj.<br />

help classname displays help for the fully qualified class, classname.<br />

help syntax displays M-file help describing the syntax used in MATLAB<br />

commands and functions.<br />

t = help('topic') returns the help text for topic as a string, with each line<br />

separated by /n, where topic is any allowable argument for help.<br />

Note M-file help displayed in the Command Window uses all uppercase<br />

characters for the function and variable names to make them stand out from<br />

the rest of the text. When typing function names, however, use lowercase<br />

characters. Some functions for interfacing to Java do use mixed case; the<br />

M-file help accurately reflects that and you should use mixed case when<br />

typing them. For example, the javaObject function uses mixed case.<br />

Remarks To prevent long descriptions from scrolling off the screen before you have time<br />

to read them, enter more on, and then enter the help statement.<br />

Creating Online Help for Your Own M-Files<br />

The MATLAB help system, like MATLAB itself, is highly extensible. You can<br />

write help descriptions for your own M-files and toolboxes using the same<br />

self-documenting method that MATLAB M-files and toolboxes use.<br />

The help function lists all help topics by displaying the first line (the H1 line)<br />

of the contents files in each directory on the MATLAB search path. The<br />

contents files are the M-files named Contents.m within each directory.<br />

Typing help topic, where topic is a directory name, displays the comment<br />

lines in the Contents.m file located in that directory. If a contents file does not<br />

exist, help displays the H1 lines of all the files in the directory.<br />

Typing help topic, where topic is a function name, displays help for the<br />

function by listing the first contiguous comment lines in the M-file topic.m.<br />
