Overloaded function.

  1. solve(A: pyopenms.MatrixDouble, b: pyopenms.MatrixDouble) -> tuple

Solve Ax=b (x>=0). Returns tuple(status, x). Copies A and b.

  1. solve(A: pyopenms.MatrixDouble, b: collections.abc.Sequence[float]) -> tuple

Solve Ax=b (x>=0) in-place. Returns tuple(status, x). Modifies A and b internally.
