Solved! Good in comsol, failed in Matlab: Illegal input vector illegal entity number

Hello every body, I am using comsol 5.4 and I built my model and solved the problem and everything went fine and a good solution was obtained in comsol. Exporting the same exact model to matlab is problematic! Exactly the same model and when running this model in matlab I got the following error:
Error using file (line 912)
Java exception occurred:
Exception:
com.comsol.util.exceptions.UnexpectedServerException: java.lang.IllegalArgumentException: Illegal input vector illegal entity number (rethrown as com.comsol.util.exceptions.FlException)

and the corresponding line is a selection set line :
model.component('comp1').geom('geom1').feature('del1').selection('input').set({'par3(12)' 'par3(7)' 'par3(4)' 'par3(2)' 'par3(5)' 'par3(11)' 'par3(6)' 'par3(9)' 'par3(10)' 'par3(8)' ... 'par3(3)' 'par3(1)'}, [1 2 3 4 5 6 7; 1 2 3 0 0 0 0; 1 2 3 0 0 0 0; 1 2 3 4 0 0 0; 1 2 3 4 0 0 0; 1 2 3 4 0 0 0; 1 2 3 4 0 0 0; 1 2 3 0 0 0 0; 1 2 3 0 0 0 0; 1 2 3 0 0 0 0; 1 2 3 4 0 0 0; 1 2 3 4 5 6 7]);
what's the problem with matlab?? thanks!

Hi Bell
It is hard to tell what goes wrong without having access to your model. What version of Comsol did you use to generate the offending line?
If you are able to share your model then please send the MPH-file to support and we will have a look.
The problem is with jagged arrays, which are allowed in Java, but not in Matlab. The solution is to split the settings into separate statements (perhaps if you do "File->Compact History" Comsol will do this for you). Something like this: model.component('comp1').geom('geom1').feature('del1').selection('input').set('par3(12)', [1 2 3 4 5 6 7]) model.component('comp1').geom('geom1').feature('del1').selection('input').set('par3(7)', [1 2 3])
etc.
should work.

You're just brilliant! It worked.
