Are there methods for computing the determinant of (large) sparse
matrices? Mathematica shuts down the kernel when I ask for
Det[iden]
where
iden = SparseArray[{i_, i_} -> 1. {10^4, 10^4}, 0.]
Of course I know the answer in this case, but more generally I'm
interested in the determinant of tridiagonal positive definite matrices.
