The tape has three files; The first file is a README file. The second file contains a program and subroutines to measure timing for the modified EISPACK routines for reducing a symemtric matrix to tridiagonal form. The third file is the code for finding the eigenvalues of a symmetric tridiagonal matrix. These programs are in the public domain and can be freely used and distributed. .sp 2 .nr VS 12 .in +5.5 Best Regards, .sp 2 Jack J. Dongarra Mathematics and Computer Science Division .
