mixed boundary condition of 2D heat conduction

Could anyone teach me how to solve the partial differential equation of 2D transient heat conduction problem with mixed boundary conditions?

The question goes like this:

The top and bottom of a rectangle are fixed at 20 and 90 degree receptively, but the left and the right sides of the rectangle are subjected to Robin boundary condition. How could I solve this mixed boundary condition problem with MATLAB?

Thanks!

Andy
