comment How can I set multiple values to local variables in a Module?
@Hyper, yes, that's precisely what m_goldberg does. That's how it is...

"only assignments to symbols are allowed" - that's right, the scoping constructs don't allow parallel assignment in the variable list.

comment Sorting Eigensystems
Have you seen the post rm linked to? (It would now seem that this is a dupe of that question.)

comment Mapping multiple functions
"anonymous function" - so, you'll also want to look at the documentation for Slot[] in addition to the one you already read for Function[]. In this case, since FindRoot[] takes two arguments, insert a slot as one of the arguments, and then you can use Function[].

Why not pair up your eigenvalues and eigenvectors, and then sort those pairs?

comment Using Or While in Select
Use Im[#] == 0 instead. (Anybody with a convenient link to the nuances of Equal[] and Set[]?)

comment Making a calculation with high precision
Hence my third sentence, @Thanos. Did you read the docs already?

comment Making a calculation with high precision
What do you mean you don't get an actual number, @Thanos? This is a number, symbolically presented. I suppose you will say that Sqrt[2] is not a number, too? In any event, look up N[], and note well what its second argument does.

comment Options which require RuleDelayed
@rcollyer, anyway, I was implicitly talking about what Oleksandr now explicitly stated; it is a bit hard to simulate human discretion. "Yes, I wanted to use -> here; stop bugging me!"
