comment How to calculate an expression to a specified number of significant digits
Is this a Mathematica question? If so, pleas show what you tried first. If not, you're in the wrong forum.

And this is a forum for Mathematica, not C++.

comment I don't understand ListCorrelate!
You can learn about the function ListCorrelate in the Mathematica documentation. However, your question is ambiguous: do you want to know what ListCorrelate does? Do you want to know what Subscript does? Do you want to know how the code you posted relates to solving PDEs? Do you want to know what {1,2} represents? You need to be more precise.

comment Solving a linear system
The first equation in Solve does not exactly match the OP's equation (40-->4), so the posted result is not correct.
