What You Must Know
| • | Library documents are stored in the MyLib folder, which is located on the TI‑Nspire™ Home screen. |
| • | By default, the MyLib folder is shown on the TI‑Nspire™ Home screen when you install the application. To hide the folder, tap Settings  > Preferences, and then select OFF. |
| • | The TI‑Nspire™ App installation includes a library document that contains Linear Algebraic functions. The library is named linalg or linalgcas. |
| • | If you delete or overwrite an installed library, you can restore it by reinstalling the TI‑Nspire™ App. |
| • | Reinstalling the TI‑Nspire™ App replaces all libraries in the default MyLib folder. If you change an object in an included library or replace an included library document with your own document of the same name, reinstalling overwrites your changes. |
| • | Library objects are global in nature and accessible from any TI‑Nspire™ document. |
| • | Library objects can be public or private. If designated as public, the library object is accessible via Utilities > Libraries. |
| • | You can use the libshortcut() command to define shortcuts to library objects. Defining a shortcut 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 private library objects. |
