Hi, I'm looking for a numerical method to solve non linear lasers equations systems : x'[t]=3D=3D(y[t]-z[t]-1)*x[t] y'[t]=3D=3Db-x[t]*y[t] z'[t]=3D=3D-x[t]*z[t] Range Kutta 4 method is provided by Mathematica, but with constant steps. Do you know how can I write Range Kutta 4 with variable steps with Mathematica ? Vincent DELAYE vincent.delaye at cea.fr Lti DSYS SCSI Grenoble (FRANCE)
