I need to solve this equation to find the right temperature profile in a metal plate following a determined heat flow on the surface. I have used computer modeling and I need to confirm the temperature profile by equations.

I did a lot of diff eq about 20 years ago. I have tried different ways I could think about and find in books or internet, but now I need a little help.

I will check for matricies.

Thanks

Does anybody could help me with the following equation:
xy"+y'-mxy=0
or
my=y"+y/x
It comes from the Laplace transform of a problem of heat conduction in polar coordinates.

Thanks
