BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-66-43 ENTRY:: January 19, 1996 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: Two working algorithms for the eigenvalues of a symmetric tridiagonal matrix TYPE:: Technical Report AUTHOR:: Kahan, William AUTHOR:: Varah, James M. DATE:: August 1966 PAGES:: 32 ABSTRACT:: Two tested programs are supplied to find the eigenvalues of a symmetric tridiagonal matrix. One program uses a square-root-free version of the QR algorithm. The other uses a compact kind of Sturm sequence algorithm. These programs are faster and more accurate than the other comparable programs published previously with which they have been compared.
