Additional Inherited Members | |
![]() | |
double | bracket_step |
The relative stepsize for automatic bracketing (default value is zero) More... | |
double | bracket_min |
The minimum stepsize for automatic bracketing (default zero) | |
size_t | bracket_iters |
The number of iterations in attempt to bracket root (default 10) | |
![]() | |
double | tol_rel |
The maximum value of the functions for success (default ![]() | |
double | tol_abs |
The minimum allowable stepsize (default ![]() | |
int | verbose |
Output control (default 0) | |
int | ntrial |
Maximum number of iterations (default 100) | |
bool | err_nonconv |
If true, call the error handler if the solver does not converge (default true) | |
int | last_ntrial |
The number of iterations used in the most recent solve. | |
This class currently uses o2scl::gsl_tolerance as a test, since this works even when the root is zero.
