public class DenseLargeDComplexMatrix3D extends WrapperDComplexMatrix3D
This data structure allows to store more than 2^31 elements. Internally holds one three-dimensional array, elements[slices][rows][2*columns]. Complex data is represented by 2 double values in sequence, i.e. elements[slice][row][2*column] constitute the real part and elements[slice][row][2*column+1] constitute the imaginary part. Note that this implementation is not synchronized.
