Efficiency of purely functional programming
...out simulating random access memory using only pointers). Pippenger also establishes that there are algorithms for which that is the best you can do; there are problems which are O(n) in the impure system which are Ω(n log n) in the pure system.
There are a few caveats to be made about this paper....
What Haskell representation is recommended for 2D, unboxed pixel arrays with millions of pixels?
...a also has a rich interface for doing so. Vector on its own does not.
Notable mentions:
hmatrix, a custom array type with extensive bindings to linear algebra packages. Should be bound to use the vector or repa types.

Pointer expressions: *ptr++, *++ptr and ++*ptr

1. Precedence. A quick glance at the precedence table for operators will tell you that postfix increment has a higher precedence (16) than dereference / indirection (15). This means that the complex expression *p++ is going to be grouped as: *(p++). That is to say, the * p...
How to calculate moving average using NumPy?
...inciple behind this answer is widely used in image processing (summed area tables they call it), so the issue had to be in the implementation. A good example of being bit by premature optimization, since I kind of recall doing the operation in-place "because it will be more efficient." On the bright...

Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?
