Re: switchcase problem in R12 v6.1

Hi,
the error message tells you what's wrong: ode15s gives t, c, and flag
to your function trial. flag has the value 'init', which is not handled by
your function, so you should write something like

function varargout= trial (t, c, flag)

switch flag
case 'init'
varargout{1}=<your initial value comes here>;
....
