Relative Acceleration Increment

In the governing equation,

\[ \mathbf{M\cdot\Delta{}A=R}, \]

this converger tests the following ratio,

\[ \mathbf{\dfrac{\left|\Delta{}A^k\right|_\infty}{\left|\sum_{i=0}^{k}\Delta{}A^i\right|_\infty}}\leqslant{}tol. \]

where \(\mathbf{\Delta{}A^k}\) denotes the acceleration increment of the \(k\)-th iteration.
