Relative Acceleration Increment

In the governing equation,

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

this converger tests the following ratio,

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

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