comment Calculate periodicity in 1-dimensional array with noise
Here's a tutorial on correlations in Mathematica. It's late here, so I don't have time to write up a complete answer.

comment How to solve integral in Mathematica?
@George, my apologies for not getting back to you sooner. I have a couple of questions. Why should $H$ be diagonal? I don't see any reason, a priori, why it should be. So, I'd check to see that c[n,m], h, and g are giving you what you expect. If not, let me know what you expect them to be, and we'll see if we can get them there.

@George, give me several hours to get back to this. I'll take a look at it then.

@George, looking at the terms in H for all $p=q$ between $5$ and $12$, they add identically to zero. For a lot of the other values of $p$ and $q$, all of the terms are identically equal to zero.

I'm assuming $x \in \mathbb{R}$?

I believe you meant to have $\frac{1}{u^2}$ inside the middle integral in line 3?

comment An optimization problem involving orthogonal matrices
@hardmath, you and Shiyu are both correct about my solution. For some reason, I though it could be moved like a matrix.
