Working with TI-Nspire™ libraries

What is a library?

A library is a TI-Nspire™ document that contains a collection of variables,
functions, and/or programs that have been defined as library objects.
Unlike ordinary variables, functions, and programs, which can be used
only within a single problem (the problem in which they are defined),
library objects are accessible from any document. You can even create
public library objects that appear in the TI-Nspire™ Catalog.
For example, suppose you have created library document
matrix
containing public library function and a private library function
trace
.
errmsg
Function calculates a rank of a square matrix. If its input is not a
trace
square matrix, calls function , which should then return an
trace errmsg
appropriate error string.
