comment Optimization for iterating and plotting a matrix product and its elements?
Regarding numerical precision - when you use Compile you are always using machine precision. Outside of compiled code you can use exact arithmetic or arbitrary precision (see the tutorial tutorial/ArbitraryPrecisionNumbers for example), but it will be much slower.

comment Optimization for iterating and plotting a matrix product and its elements?
The square rooted term in the function appears 3 times and is quite complicated. It will be faster if you compute it just once like you do with t. Other than that I can't see any obvious optimisations.

Maybe you can use some simpler, shorter functions to make a working example. It's really hard to optimise code just by looking at it - people really need something they can paste into Mathematica and play with. BTW you can use Dot for matrix multiplication.

Your posted code includes symbols o,A,C,D in the complied function, but they are not defined anywhere. You should avoid using C and D anyway as they are built-in functions.

@MartinBüttner, regarding the linked question RunnyKine's answer here gives four empty lists if you remove the Union bit.
