instrhelp

Help for instrument object type, function, or property

Syntax

instrhelp
instrhelp('name')
out = instrhelp('name')
instrhelp(obj)
instrhelp(obj,'name')
out = instrhelp(obj,'name')

Arguments

'name'

A function name, property name, or instrument object type.

obj

An instrument object.

out

The help text.

Description

instrhelp returns a complete listing of toolbox functions, with a brief description of each.

instrhelp('name') returns help for the function, property, or instrument object type specified by name.

You can return specific instrument object information by specifying name in the form object/function or object.property. For example, to return the help for a serial port object's fprintf function, name would be serial/fprintf. To return the help for a serial port object's Parity property, name would be serial.parity.

out = instrhelp('name') returns the help text to out.

instrhelp(obj) returns a complete listing of functions and properties for obj, with a brief description of each. Help for the constructor is also returned.

instrhelp(obj,'name') returns help for the function or property specified by name associated with obj.

out = instrhelp(obj,'name') returns the help text to out.

Examples

The following commands illustrate some of the ways you can get function and property help without creating an instrument object.

instrhelp gpib
out = instrhelp('gpib.m');
instrhelp set
instrhelp('gpib/set')
instrhelp EOSCharCode
instrhelp('gpib.eoscharcode')

The following commands illustrate some of the ways you can get function and property help for an existing instrument object.

g = gpib('ni',0,1);
instrhelp(g)
instrhelp(g,'EOSMode');
out = instrhelp(g,'trigger');

Tips

When returning property help, the names in the See Also section that contain all uppercase letters are function names. The names that contain a mixture of upper and lowercase letters are property names. When returning function help, the See Also section contains only function names.

You can also display help via the Workspace browser by right-clicking an instrument object, and selecting Instrument Help from the context menu.
