The updated material follows. In the next mail message, I have an updated version of napack/cg.f -- please replace the old version with this one. Thank you. Bill (hager@math.ufl.edu) NAPACK A collection of Fortran subroutines to solve linear systems, to estimate the condition number or the norm of a matrix, to compute determinants, to multiply a matrix by a vector, to invert a matrix, to solve least squares problems, to perform unconstrained minimization, to compute eigenvalues, eigenvectors, the singular value decomposition, or the QR decomposition. The package has special routines for band, symmetric, indefinite, tridiagonal, upper Hessenberg, and circulant matrices.

Thank you Bill ... From math.ufl.edu!hager Tue Sep 10 18:39:22 EDT 1991 Subject: replacement for subroutine bvert in napack Eric, please replace bvert in napack by the following routine. Also, could you please send me the email addresses of all people who obtained a copy of bvert from napack? Thank you. Bill ...

Would you also replace the routines fft and ffc in napack by the ones appearing in the next 2 messages -- although I am only changing 1 line in a comment statement, I guess it's easiest to replace the entire routine. Thanks, Bill .
