monarch_dodra:
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.
