<p>The function allows choosing a simulation method (<code>Newton</code> or <code>Gauss</code>), selecting the number of periods and a starting date. Specifying an initial period is optional; if omitted, periods will simply be numbered consecutively with natural numbers.</p>
<p>By default, equations are solved using the Gauss method. Independent equations for a specific period are resolved in a single iteration. Interdependent equations are grouped into loops and solved itera
