Hello,
a few questions about lsode:
1) is lsode_options() persistant ? I mean, if I set some param, will
it stay forever of should the call be repeated each time before
lsode() itself ?
2) I'm trying to integrate the function
xdot= a2 Il^2 + a1 Il + b3 x^3 + ...
where Il is a function of time, a2, a1, b3, ... are constant
about the jacobian: is this correct:
jac = 3 b3 x^2 + 2 b2 x + ...
what about t ? what about terms like 2 a2 Il dIl/dt ?
Thanks in advance
Pascal
