Dmitri,
Octave 2.9.x builds fine without UMFPACK, but can't solve full sparse
equations, though with the use of the LAPACK tridiagonal and banded
solvers and code for back substitution for triangular matrices it can
still solve many cases... Try
a = 100*speye(100,100) + sprandn(100,100,0.05);
[l,u,p] = lu (a);
and I'll bet you get an error, since the LU function won't find UMFPACK
and will fail with an error...
Cheers
David
