WebWhat ode45 does is to estimate the solution (of one step) with two Runge–Kutta methods with local orders of 4 and 5, respectively (hence those numbers). It uses the solution of the 5 th -order method to estimate the solution of the ODE and the difference between the solutions from the two methods to estimate the error of the integration. WebApr 11, 2024 · I was using ode45 with 'options' defined as: options = odeset ('RelTol',1e-10,'AbsTol',1e-10); [t1,y1] = ode45 (@ (t,y)disc_dy (t,y,delta,g,C,N,F,H),tspan,y0,options); When tried to run the code above, errors pop up as follows: Error using odeget Unrecognized property name 'NonNegative'. See ODESET for possibilities. Error in ode45 (line 158)
