Group Hohn
Group Description |
Single-material crack problem, Michael Hohn, Univ. of Utah. The included files contain the matrices and rhs vectors arising in two ways of discretizing a single-material crack problem. The *coord files are in zero-indexed coordinate format (row, column, value); the *vec files contain -- the size N -- the entries from first to last The fd-* files come from a finite difference approximation; the sinc-* files from a sinc-basis approximation. Both use the same logarithmic grid. The fd matrices are very sparse, and factor in a few seconds, so they're not terribly interesting, but the sinc matrices are another matter... Larger matrices available on demand :) -- Michael Hohn, hohn :at the domain: math.utah.edu |
