how can i set the boudary condition ? that changes its temperature with respect to time?

i am trying to solve a hollow cylinderical problem using pdetool in matlab. i want to set the bondary conditions in such a way that the outer side of cylinder contains constant temperature (120 Centigrate), while the heat will transfer from outer to inner surface. and the temperature of inner surface must be changed with respect to time. the initial conditions is at room temperature.

how can i set my boundary conditions for inner surface that its temperature changes with respect to time.??

It depends on your MATLAB version. For R2014b or R2015a, follow this method to specify nonconstant boundary conditions. For earlier MATLAB versions, use this technique.
