As a continuation of my previous question, Simon\'s method to find the list product of a PackedArray is fast, but it does not work with negative values.
In Mathematica a vector (or rectangular array) containing all machine size integers or floats may be stored in a packed array.These objects take less memory, and some operations are much faster on the
In C/C++ you always have SizeOf(array[N] of T) = N * SizeOf(T); In Pascal/Delphi you can use \'packed array\' to be sure that the above assert is true, but does \'packed\' specifier have any practi
How can I \"pack\" and \"write\" a struct to a file using C so that: struct a { uint64_t a; char* b; uint16_t c;
