ME43: Sparse unsymmetric system: row-by-row frontal method

To solve one or more sets of variable-band complex linear equations, \(\mathbf{Ax} = \mathbf{b}\), \(\mathbf{A} ^ T \mathbf{x} = \mathbf{b}\) or \(\mathbf{A} ^ H \mathbf{x} = \mathbf{b}\), by the frontal method (\(\mathbf{A} ^ H \mathbf{x} = \mathbf{b}\) is the transpose of the complex conjugate of \(\mathbf{A}\)). ME43 provides the user with a straightforward interface to the HSL routine ME42 when entry is by equations and auxiliary storage is not required. If the user requires more sophisticated facilities, ME42 should be employed.
