[Bug-gsl] gsl_odeiv_evolve_apply can only decrease step size, not increase

2016-10-13 Thread Chris Rogers
I am using gsl v1.15 I note that ODE evolver, gsl_odeiv_evolve_apply, defined in gsl-1.15/ode-initval/evolve.c, can only decrease the step size in the integration. If I define a control function that results in an increasing step size, the evolver does not increase the step size. For example
