WebDirect solvers do a full factorization of the system matrix, which can take quite a while and use a lot of memory. However, once such a factorization is done, the system can efficiently be solved for any number of right-hand sides. For direct solvers a number of readymade libraries exist. This makes using direct solvers relatively straightforward.

WebNotice that the rows of the coefficient matrix (corresponding to equations) outnumber the columns (corresponding to unknowns), meaning that the system is overdetermined.
