how can i solve this please: Consider an ?×? cm fin, with d mm thickness. Assume that power W is supplied along the [a,b] interval on the left edge. According to Fourier’s first law heat energy per unit time, q, is ? = −?∇? where ? is the thermal conductivity constant of the material; ? is the cross-sectional area of the material; ∇? is the gradient of the temperature. Newton’s law of cooling defines q in terms of convection: ? = −?(? − ??) where ? is the convective heat transfer constant of the material; ?? is the ambient temperature. Based on that formulate the 2D discrete mathematical model, based on the elliptic PDE with Robin (convective) boundary conditions.

What do you have so far? What about this are you trying to accomplish in Matlab?

You can use PDE Toolbox to solve this kind of heat transfer problem. Refer to the documentation on Heat Transfer problem setup in PDE Toolbox.
