Ode23 in Simulink Matlab function block

I have a function in matlab, on which ode23 is implemented. How to implement ode23 in Simulink if I want to have the same function in Simulink ? The code generates the differencial values which are integrated using ode23 in matlab. Can you help me understand the equivalent implementation method in Simulink?

Hi Shubhada,

I understand that you are trying to implement the same function in Simulink that is implementing Ode23 in MATLAB. Please follow the below mentioned steps to do this:

• Create a Simulink model and open it.
• Add an ODE solver block to the model, such as the "Solver Configuration" block. Set the solver type to ode23 and specify any relevant solver options.
• Use the "MATLAB Function" block to implement your MATLAB function to this model.
• If your function has inputs and outputs, connect them to the corresponding blocks.
• Configure the simulation settings, such as the start and stop times and the simulation solver options.
• Run the simulation and observe the results.

I hope this helps you get started with implementing the ode23 function in Simulink.
