### MA43 Sparse unsymmetric system: row-by-row frontal method

To solve one or more sets of variable-band linear equations, $Ax=b$ or ${A}^{T}x=b$ by the frontal method.

MA43 provides the user with a straightforward interface to the HSL routine MA42 when entry is by equations and auxiliary storage is not required. If the user requires more sophisticated facilities, MA42 should be employed.
