MTH 365/465 Numerical Linear Algebra (Spring 2018):
This course provides an introduction to numerical linear algebra, the study of algorithms for finding numerical solutions of linear algebra problems. Topics include direct and iterative methods for the solution of systems of linear equations, matrix decompositions (including singular value decomposition and its applications), computation of eigenvalues and eigenvectors, relaxation techniques, the theoretical basis for error analysis, including vector and matrix norms, applications such as least squares and finite difference methods. Course syllabus.
 Instructor: Dr. Sofya Chepushtanova, office SLC 410, email: sofya.chepushtanova@wilkes.edu.
 Class meetings: MWF 12:0012:50am, room SLC 411 (we will also meet in SLC 409 for labs).
 Office hours: MWF 10:0010:50am and 2:002:50pm or by appointment, SLC 410.
 Textbook: Numerical Methods: Design, Analysis, and Computer Implementation of Algorithms by Anne Greebaum and Timothy Chartier, Princeton University Press, 2012.
 MATLAB is our programming language for this course, it is well suited to linear algebra computations. To start, read Chapter 2 of the textbook. MATLAB is available for use in both labs 409 and 431.
A couple of useful MATLAB resources:
 Here you can find video lectures "Using MATLAB for the First Time" from MIT OpenCourseWare.

Numerical Computing with MATLAB
is an archive of MATLAB programs of basic numerical algorithms,
it is good both for beginners and advanced MATLAB programmers.
 LaTeX: a markup language to typeset documents. It excels at making math and the overall layout beautiful. You can use it to type your homework solutions, and I encourage you to do so. Read the tutorial here. You may find the following LaTeX cheatsheet useful. I will post the LaTeX files for all homework assignments throughout the semester.
