error message when define interpolating function in matlab (other function types work, in comsol it works as well)

Hello everybody,

whenever I define an interpolation function in matlab with

model.func.create('int1', 'Interpolation');

I get an error message (see below) - but if I write instead "model.func.create('ana1','Analytic');" or the same with 'MATLAB', the problem does not occur. Using the COMSOL interface directly, it works fine (it is just the exported model from comsol that I try to solve via the skript instead).

Does anyone have the same problem? This weird problems popping up drive me crazy :(

All best :)
Sabine
