Hello all

I am running a model in Simulink. I want 2 values from the model to input into a look up table while the simulation is running. I tried the dynamic look up table but the it take one value at every time instant. What I want is that these values should get stored as an array(2 columns) and get accumulated in the table during the simulation. Is this possible? could anybody help me out with this?

Thank you! James

Do you want to change the 'Vector of input values' and 'Table data' properties of lookup table during run time?

Yes...that is exactly what I want to do...I was thinking if I could access the internal buffer of the 'To workspace' block and feed it to a dynamic look up table. But I don't know is that is actually possible.

You may want to try using the Data Store Memory (DSM) block instead of the Look Up Table (LUT).

You can then use the MATLAB Function block to modify the DSM and/or to create your own LUT based on the DSM.

HTH.

Hello Rick

Actually I need to use the look up tables because the look up is not based on a particular function or relation. It is simply matching from the table data. I tried using DSM but the problem is I need the data from the DSM to get into the dynamic lookup table as an array(created while running the simulation) and this should constantly keep updating during the simulation time. I hope I am expressing my problem properly.

Thanks James
