Solving a system of linear equations with a matrix with 5 diagonals is
done pretty well by LinearSolve. But since I work with large matrices,
and all of them have only 5 nonzero diagonals, I don't have to use
memory for the nonzero entries in order to give LinearSolve a "good and
Does anybody know how could I, for example, do some transformation from
5 to 3 diagonals and then use TridiagonalSolve? I would
appreciate any help. Thanks!
