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

To solve one or more sets of variable-band linear equations, \(\mathbf{Ax} = \mathbf{b}\) or \(\mathbf{A} ^T \mathbf{x} = \mathbf{b}\) 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.
