cern.colt.matrix.tlong.LongFactory3D
public class LongFactory3D
Factory for convenient construction of 3-d matrices holding int cells. Use idioms like LongFactory3D.dense.make(4,4,4) to construct dense matrices, LongFactory3D.sparse.make(4,4,4) to construct sparse matrices. If the factory is used frequently it might be useful to streamline the notation. For example by aliasing:
LongFactory3D F = LongFactory3D.dense; F.make(4,4,4); F.descending(10,20,5); F.random(4,4,5); ... |

The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa.
