Comsol with Matlab: treat a Matlab-Vector from Workspace as Function

I want to use Comsol in Matlab, because most of my previous calculations have been done there. My question is now, how to import my solutions into the Comsol-Model.
The vector Yi includes all my solutions depending of the time. For the first test, I defined a point in Comsol, which should have my solution as voltage.
My first try was this one:
pnt.V0 = {0,'Yi(ceil(t/0.00001)+1)'};
but Matlab gave back the error-message, that Yi wasn't defined in Comsol. So my question is now, how I can define it. In my opinion, I could use this code:
clear fcns
fcns{1}.type='interp';
fcns{1}.name='Yi';
fcns{1}.method='neighbor';
fcns{1}.extmethod='interior';
fcns{1}.x={0:Ts:10};
fcns{1}.data={Yi};
fem.functions = fcns;
but it didn't work out. It's my first time with comsol in Matlab but the Matlab Interface Guide and the Search function were not able to help me.
Thank you very much for your fast answers.
