Exact solution of these large systems (complete decomposition in<br />
eigenvector basis or exponential matrix of A) not possible in<br />
practical applications. Therefore: recursive solution. We distinguish:<br />
i explicite<br />
and implicite recursion, depending on the formula for a<br />
new value: explicite or affording to solve an equation or a system<br />
of equations<br />
i single and multi ple step method s, depending<br />
on the number of<br />
old values taken into account. Linear single step methods may be<br />
( m + 1) ( m ) ( m )<br />
written as y = Gy + q with the recursion matrix G.<br />
