/*
Purpose:
Call basiclu_solve_sparse() on a BASICLU object. On success, the solution
is provided in obj->lhs and the nonzero pattern is stored in
obj->ilhs[0..obj->nzlhs-1].
Return:
BASICLU_ERROR_invalid_object
obj is NULL or initialized to a null object.
Other return codes are passed through from basiclu_solve_sparse().
Arguments:
struct basiclu_object *obj
Pointer to an initialized BASICLU object.
The other arguments are passed through to basiclu_solve_sparse().
