ODE Solver Validation #59

Closed rdoddanavar closed 3 years ago

rdoddanavar commented 3 years ago

Quick check w/ MATLAB's ode45 to make sure my solver in GSL is working; 1DOF, no atmos/drag, just thrust & gravity

rdoddanavar commented 3 years ago

Do I really understand relative & absolute error tolerances for ODE solvers? Probably not

rdoddanavar commented 3 years ago

From MATLAB's doc: ode45 is based on an explicit Runge-Kutta (4,5) formula, the Dormand-Prince pair.

Pretty sure I don't have this one in GSL, but instead the rkf45 method
