MAT 342 is a linear algebra course
at the sophomore/junior level, intended primarily for mathematics,

science and engineering students.
The goal of the course is to impart
the concepts and techniques

of modern linear algebra (over the
real scalar field) with a significant
level of rigor.

The prerequisite is coregistration
in MAT 272.

The successful student will be able
to write clearly about the concepts of linear algebra,

(definitions, counterexamples, simple
proofs), and to apply the theory
to examples.

Some exposure to the practical nature
of solutions of linear algebra problems is healthy.

On the other hands, sophisticated
numerical algorithms should not be presented.

Use of computers to work numerous
problems often can enhance the student’s understanding

of the material. It
is suggested that a software package be made available to the students,

but that classroom discussion of
computers be limited. Instructors
are encouraged,

but not required, to make use of
computers in the course.

Below is a list of **recommended
topics**, together with approximate class times for each section.

If time permits, applications (e.
g. least-squares, LU decomposition, difference equations,

dense vs. sparse matrices, etc.),
or an introduction to complex vector spaces may be included.

# Systems of linear equations and
matrices
(6 50-minute classes)

Gauss-Jordan elimination, homogeneous
systems, matrix algebra, elementary matrices, inverses

# Determinants
(3 50-minutes classes)

by row reduction and cofactor
expansions, Cramer’s rule

# Vector Spaces
(9 50-minutes classes)

Euclidean space, general (real)
vector spaces, subspaces, linear independence,

dimension, row, column and null
spaces

# Inner products
(5 50-minutes classes)

norms, orthogonal bases and Gram-Schmidt
orthogonalization

# Linear transformations
(8 50-minutes classes)

Kernel and range, inverse transformations,
matrices of linear transformations,

change of basis, similarity

# Eigenvalues and eigenvectors
(7 50-minutes classes)

diagonalization, orthogonal diagonalization
and symmetric matrices, quadratic forms
