A possible root cause of the issue can be repeating time values in the experimental data which get indirectly fed to 'OutputTimes' within Configuration Parameters when called by Simulink.
- To verify this :
You may check non unique time values in data by executing the following command:
length(unique(Your2dvector(:,1))
To cause the error, this value might be smaller than the length of your experimental data.
- Approach to removing duplicate entries:
We can average the values of repeating column entries and get a unique array of elements. I would suggest backing up your experimental data before doing the matrix operations below.
array = [1 10; 2 20; 3 30; 4 40; 4 50; 4 60; 5 70; 6 80; 7 90; 7 100; 8 110];
[C,ia,idx] = unique(array(:,1),'stable');
val = accumarray(idx,array(:,2),[],@mean);
your_mat = [C val]
