deSolve: Problem solving ODE including modulo-operator
I have a problem integrating the 'standard map' ( http://en.wikipedia.org/wiki/Standard_map http://en.wikipedia.org/wiki/Standard_map ) with deSolve: By using the modulo-operator '%%' with 2*pi in the ODEs (standardmap1), the resulting values of P and Theta, should not be greater than 2pi. Because this was not the case, i was thinking that the function 'ode' has some internal problems with the '%%' or integrating periodical ODEs, so I wrote a modulo-function by myself (modulo and standardmap2). But...
