    • Text

    Linear Algebra, 4th edition, by Stephen Friedberg, Arnold Insel, and Lawrence Spence is available in local bookstores.
  • A list of errata is available, including homework questions.
  • There are many good books on linear algebra. You can use the math department course archives to see which texts have been used in previous years. Reading several presentations of one topic is often helpful.
  • One book used in the past is Linear Algebra Done Right by Sheldon Axler. It is based in part on ideas from his article Down with Determinants!, which you might enjoy reading.
  • You may also want to look at the webset for my graduate numerical linear algebra course Math 221, to see practical algorithms for solving linear equations, finding eigenvalues, etc. My course on parallel computing CS 267, discusses how these algorithms are implemented on parallel computers.

    • Course outline in pdf or postscript. (last updated Aug 29, 10:20am)

  • This includes topics to be covered and grading policies. You are responsible for reading this and knowing the course rules about late or missing assignments, etc.

    • Teaching Assistants and Sections

  • TA office hours during finals week are posted

    • Enrollment Issues

  • Barbara Peavy (967 Evans Hall, 642-2479, peavy@math) is in charge of all enrollment issues, so please direct all queries to her, including how to get off the waitlist. We do not anticipate any enrollment problems based on space.

  • National Academy report on the future of supercomputing, including the role of linear algebra.
  • UC Berkeley course on Parallel Computing, including how to implement various linear algebra algorithms in parallel.
  • LAPACK is one of the most popular packages of linear algebra software available. LAPACK is used by Matlab. Its version for parallel computers is called ScaLAPACK.
  • When eigenvalues go bad
  • Video and other information about collapse of Tacoma Narrows Bridge
  • Video and other information about vibrations of Millennum Bridge (look at "Oscillation" on "Challenge" pull-down menu)
