I do not see essentially any difference between the different methods for large matrices, between Numpy, Ctypes and Fortran. (Fortran instead of C++ --- and if thi...
Algorithm to compare two images
...hard though), so it may be a lot of work for you with limited/no results.
Zipping
Ow's answer in this question is excellent, I remember reading about these sort of techniques studying AI. It is quite effective at comparing corpus lexicons.
One interesting optimisation when comparing corpuses is t...
What's the difference between equal?, eql?, ===, and ==?
...uals(o)
ops = [:==, :===, :eql?, :equal?]
Hash[ops.map(&:to_s).zip(ops.map {|s| send(s, o) })]
end
end
"a".all_equals "a" # => {"=="=>true, "==="=>true, "eql?"=>true, "equal?"=>false}
== — generic "equality"
At the Object level, == returns true only if obj and othe...

the basic rule to understand cmake commands is the following syntax:

Why is the order in dictionaries and sets arbitrary?
...ctionary in between. That means that d.items() is essentially identical to zip(d.keys(), d.values()). If any items are added to the dictionary however, all bets are off. The order could change completely (if the hash table needed to be resized), though most of the time you'd just find the new item t...
