COmsol - Matlab Variable linking.

Hi all,

I am Looping simulations over matlab with different sets of values matlab calculates.
I am looking for changing the variable values. I have found for Parameter as
model.param.set() for changing the Parameter values. I am looking a similar solution for the variable in the model. I Need to replace this with the Array of values. This variable is an time dependent function. and I am running an transient Analysis.

Suggest me some Options and solution to overcome this.
