[ACCEPTED]-SetLength on multidimensional array-pascal
var arr: array of array of real; ... SetLength(arr, 10, 20); // creates a 10 by 20 matrix
A bad, but equivalent, way of doing this 1 is to do
SetLength(arr, 10); for i := low(arr) to high(arr) do SetLength(arr[i], 20);
The latter approach allows "non-rectangular" arrays, however.
