Detailed Description

template<class param_t, class func_t = ode_funct<param_t>, class vec_t = ovector_view, class alloc_vec_t = ovector, class alloc_t = ovector_alloc>
class nonadapt_step< param_t, func_t, vec_t, alloc_vec_t, alloc_t >

An non-adaptive stepper implementation of adapt_step.

This class simply calls the specified ODE stepper without any attempt to modify the size of the step, and is primarily useful to allow for simple comparisons between adaptive and non-adaptive solution. To modify the ODE stepper which is used, use the adapt_step::set_step().

Idea for future:
Modify so that memory allocation/deallocation is only performed when necessary

virtual int astep ( double &  x,
double &  h,
double  xmax,
size_t  n,
vec_t &  y,
param_t &  pa,
func_t &  derivs 
) [inline, virtual]

Make an adaptive integration step of the system derivs.

This attempts to take a step of size h from the point x of an n-dimensional system derivs starting with y. On exit, x and y contain the new values at the end of the step and h contains the size of the step.

Reimplemented from adapt_step.
