public class DenseLargeFloatMatrix3D
Dense 3-d matrix holding float elements. First see the package summary and javadoc tree view to get the broad picture.
Implementation:
This data structure allows to store more than 2^31 elements. Internally holds one three-dimensional array, elements[slices][rows][columns]. Note that this implementation is not synchronized.
Time complexity:
O(1) (i.e. constant time) for the basic operations get, getQuick, set, setQuick and size.
