comment How to solve correctly inside a DO loop and then plot
sure, I just didn't want to obfuscate the important changes, that help to solve the main problem.

comment Plotting Fourier spectrum versus frequency of a signal
For startes you should use FourierDST - the discrete sine transform. But the peak's position still depends on the sample size.

comment Simulation code performance tuning
Is there some very specific function of Mathematica that you are using? It looks like a lot of loops with rather simple math in them. Here I would suggest not to use Mathematica if performance and scalability matters. In my experience you can speed up programs by roughly a factor of 1000 (non optimized Mathematica) if you switch to C/C++. Even when you optimize your code you wont reach that performance with Mathematica.

comment Performing matrix multiplications with a list
In principle I would be fine with it, I just think that we might be in different time zones (so chat would be problematic, besides the usual math typing trouble) and I would have to read about the HAC standard errors before I can give understandable help.

comment Faster way to test if an expression equals zero
could you had the expressions (at least a few hundred) somewhere externally. that would help to do some testing on our own and not just guessing.
