| Data Acquisition Toolbox | |
This section provides descriptions of all toolbox functions that you can use directly. In Functions Grouped by Category, the functions are summarized according to usage. In Functions Listed Alphabetically," the functions are described in detail.
Getting Command Line Function Help
To get command line function help, you should use the daqhelp function. For example, to get help for the addchannel function, type
daqhelp addchannel
Alternatively, you can use the help command.
help addchannel
However, the Data Acquisition Toolbox provides "overloaded" versions of several MATLAB functions. That is, it provides toolbox-specific implementations of these functions using the same function name.
To get command line help for an overloaded toolbox function using the help command, you must supply one of two possible class directories to help.
help daqdevice/function_name help daqchild/function_name
Note that the same help information is returned regardless of the class directory specified.
For example, the Data Acquisition Toolbox provides an overloaded version of the delete function. To obtain help for the MATLAB version of this function, type
help delete
You can determine if a function is overloaded by examining the last section of the help. For delete, the help contains the following overloaded versions (not all are shown).
Overloaded methods help char/delete.m help scribehandle/delete.m help scribehgobj/delete.m . . . help daqdevice/delete.m help daqchild/delete.m
So, to obtain help on the toolbox version of this function, type
help daqdevice/delete
For more information on overloaded functions and class directories, refer to MATLAB Classes and Objects in the Help browser.
