I've made a few adjustments, but now the code doesn't work anymore... Can someone help me? <br /><br />This is my system: <br />u' = By - Cu<br />y' = uz - y<br />z' = - uy - (z-1)<br />with B=127 en C=3 <br />This is Vallis sytem for El Niño. But I don't know the initial condition for this system. Maybe I can try some values?
