This chapter documents the linear algebra functions provided in Octave. Reference material for many of these functions may be found in Golub and Van Loan, Matrix Computations, 2nd Ed., Johns Hopkins, 1989, and in the LAPACK Users’ Guide, SIAM, 1992. The LAPACK Users’ Guide is available at: http://www.netlib.org/lapack/lug/
A common text for engineering courses is G. Strang, Linear Algebra and Its Applications, 4th Edition. It has become a widespread reference for linear algebra. An alternative is P. Lax Linear Algebra and Its Applications, and also is a good choice. It claims to be suitable for high school students with substantial mathematical interests as well as first-year undergraduates.
