Accessing variable (current and previous time steps) for use in a MATLAB function block during simulation in Simulink.

Hi, I have attached a screenshot of my simplified Simulink model below. In the MATLAB function block I require access to the variable value at the current and previous timesteps. In other words, a vector of historic variable values, starting at t = 1, and appended at each time step to include the most recent value. Thus far I have only been able to find solutions that would allow me to access the data when the simulation is paused or completed (e.g To Workspace). Are there perhaps any solutions to access the data whilst the simulation is running?

Hi Sune,

It is my understanding that you want to access data continuously when the simulation is running.

Please refer to the follwing documentation link for the recommended technique:

Access Block Data During Simulation

Hope this helps!

Hi Samyuktha,

Thank you! I will have a look at the linked documentation
