Numerical Heat Transfer project (Matlab required) -- 2

The attached problem set is fairly self explanatory. In this problem I am more concern with the numerical portion being done (c-e). It must be completed in Matlab as that is the only language and software I am a little familiar with. I am currently working part a and b of the problems myself, but If you think you can solve those portions easily then maybe we can discuss adding those to the bid as well. If needed I can send more files that may help with the approach, but I'm really looking for someone that can handle in a quick manner of time (2-3 days). Also attached is a power point on this type of problem that may help as well. Most of what you need is in the Power point the code writing shouldn't be too long.
