TOMS470
Linear Systems with Almost Tridiagonal Matrix
TOMS470
is a FORTRAN77 library which
implements ACM TOMS algorithm 470, for solving a linear
system with an almost tridiagonal matrix.
The text of many ACM TOMS algorithms is available online
through ACM:
http://www.acm.org/pubs/calgo
or NETLIB:
http://www.netlib.org/toms/index.html.
Languages:
TOMS470 is available in
a FORTRAN77 version.
