Hi! Thanks for your quick respond, here I’ve written a script that builds the model, performs the analysis, prints it and tries to plot it. The same error happens again but I’m suspicious the is a problem with my MatLab distribution (I’m currently using R2015 and I’ve checked that the statistics toolbox was installed). Maybe you can point me an error in my sintaxis.
EDIT:
I have also tried uq_Example_Inversion_01_Beam and the same error pops up so maybe there is some issue with my MatLab Instalation
