I need to solve the temperature distribution of a plate. And the number of nodes are 51. Hence 51 equations.

As you can see in the link, some of the equations are shown.

How to solve that using Matlab?

I know I can always separate the temperature, like [A][T]=[B]
T=inv(A)*(B)

But let say I don't want to separate the equations. I want to leave it that way. How can I solve it?
