Both ODEs are using the same time step([0:100]), and the first ODE function used to solve for 'Wa' was set up in the same fashion. The only difference is that it didn't have a separate input, only its time and initial conditions.
WebJan 22, 2010 · To solve this ODE, you must pass the data sets to the derivative function as additional parameters. When the ODE solver calls the derivative function, it will pass a specified time as the first input argument. You must then interpolate the datasets to obtain the value of the time-dependent terms at the specified time. WebSep 26, 2024 · MATLAB’s Built-In Methods. Due to its popularity, let’s start with MATLAB’s built in differential equation solvers. ... Thus MATLAB’s ODE solver suite can become more efficient by using methods which reduce the number of function calls (which multistep methods do). But this isn’t the only case where efficient methods are missing.
