Hi everybody,

I'm trying to set up a parameter optimization for a simulink model. I've tested it on a very simple model and it worked good after I figured out what's what. Now, however, I'm trying to run it on a more complex model with a couple of lookup-tables, multiple layers and so forth and I get an error message once I click on "Estimation" in the "Control and Estimation Tools Manager" window (opens after I click on "Analysis" and then "Parameter Estimation..."). The error message says: "The value of the "Value" property must be a real-valued double array." This occurs even without me loading any Transient Data or specifying any Variables. I've checked all lookup-tables with isreal(name of the lookup-table) and they all turn out as being real. I've also set the output data type of the lookup-tables to double, but that didn't help either. I hope you guys can help me with this, I'm pretty much out of reasonable ideas.

Thanks Johannes

Funny enough, I just found the issue. One of the lookup-tables had an empty cell in A1 in the imported csv file which was imported as NaN. Apparently everything except the parameter estimation is absolutely fine with that, since the value in A1 or 1-1 is not used in the model. Anywho, putting in a 0 solved the issue. Maybe this is going to help someone else in the future :)
