2. Open the TI-Nspire™ application in which you want to use the variable, function, or
program.
Note: All applications can evaluate functions, but only the Calculator and Notes
applications can run programs.
3. Type the name of the object, such as lib1\func1().
In case of a function or program, always follow the name with parentheses. To
type the “\” character on the handheld, press g p.
4. If arguments are required, type them inside the parentheses.
Creating Shortcuts to Library Objects
You can make the objects in a library more easily accessible by using libShortcut() to
create shortcuts to them. This creates a variable group in the current problem that
contains references to all the objects in the specified library document. You can choose
to include or exclude the private library objects.
For example, suppose the library document linalg contains functions named clearmat,
cofactor, gausstep, help, inversestep, kernelbasis, rank, and simultstep. Executing
libShortcut(“linalg”,“la”) would create a variable group containing the following
members:
la.clearmat
la.cofactor
la.gausstep
la.help
la.inversestep
la.kernelbasis
la.rank
la.simultstep
You can refer to those library objects from within the current problem by typing their
variable names or by selecting them from the Variables menu.
For more details about using libShortcut(), see the Reference Guide.
Included Libraries
To help you get started with libraries, the TI-Nspire™ Software installation includes a
library document with useful Linear Algebra functions. The library is named linalg or
linalgCAS and is installed in the designated library folder.
Note: Updating the handheld’s operating system or reinstalling the computer software
places all included libraries in the default folder. If you have edited an object in an
included library or replaced an included library with your own document of the same
name, updating or reinstalling will overwrite your changes. This could also happen
after batteries are replaced or the handheld system is reset.
