If all (but last of) the dimensions are known at compile time, then you
can dynamically allocate an array of fixed sized arrays:
//----
enum size_t gridSize = 4_000;
enum size_t total = gridSize * gridSize;
static assert (total == 16_000_000); //16 million doubles total
static assert (total * double.sizeof == 128_000_000); //126 Megs
allocated
void main()
{
double[gridSize][] gridInfo = new double[gridSize][](gridSize);
}
//----
This will give you a dense array: Eg: all the data is contiguous in
memory.
Nice. This idiom should be added to the D docs.
Wow, this is something I didn't know was possible. Very useful!
BTW, "all (but last of) the dimensions" isn't correct, you know them all
in your example, and it looks great!
