This Application runs in Maple. Don't have Maple? No problem!
OBJECTIVES: • To provide a collection of the necessary definitions of, and concepts associated with, matrices. • To present notational conventions adopted for all the Units. • To introduce Maple’s library package linalg containing functions required for matrix operations. • To introduce the concepts of a one-dimensional list or array and two-dimensional list or list of lists. • To introduce Maple’s type-checking function type and the Boolean values true; and false; returned by it. • To show alternative methods of defining and inputting matrices with Maple. • To illustrate methods of creating matrices whose elements depend on their location in a matrix. • To show alternative methods of substituting data for matrix elements. • To show alternative methods of evaluation of matrices entered with symbolic elements whose numerical values become known in a later phase of computation. • To introduce the rule of last-name evaluation used by Maple as applied to matrices and illustrate its implications. • To specify the functions from outside of the linalg package, which are contained in Maple’s main library and are able to perform operations on matrices. • To present alternative methods of unassigning a matrix structure from a name.
