The driver object is a high level wrapper that combines the evolution, control and stepper objects for easy use.
These functions return a pointer to a newly allocated instance of a
driver object. The functions automatically allocate and initialise the
evolve, control and stepper objects for ODE system sys using
stepper type T. The initial step size is given in
hstart. The rest of the arguments follow the syntax and
semantics of the control functions with same name
The function sets a minimum for allowed step size hmin for driver d. Default value is 0.
The function sets a maximum for allowed step size hmax for
driver d. Default value is
The function sets a maximum for allowed number of steps nmax for driver d. Default value of 0 sets no limit for steps.
This function evolves the driver system d from t to
t1. Initially vector y should contain the values of
dependent variables at point t. If the function is unable to
complete the calculation, an error code from
gsl_odeiv2_evolve_apply is returned, and t and y
contain the values from last successful step.
If maximum number of steps is reached, a value of
is returned. If the step size drops below minimum value, the function
GSL_ENOPROG. If the user-supplied functions
defined in the system sys returns
function returns immediately with the same return code. In this case
the user must call
gsl_odeiv2_driver_reset before calling this
This function evolves the driver system d from t with
n steps of size h. If the function is unable to complete
the calculation, an error code from
gsl_odeiv2_evolve_apply_fixed_step is returned, and t and
y contain the values from last successful step.
This function resets the evolution and stepper objects.
The routine resets the evolution and stepper objects and sets new initial step size to hstart. This function can be used e.g. to change the direction of integration.
This function frees the driver object, and the related evolution, stepper and control objects.
