WebIn Maple, construction of a Matrix or Array actually constructs two main objects, an rtable object, and an associated piece of one dimensional (1-D) memory (data space) used to store the contents of the rtable. The order = Fortran_order or order = C_order option describes how the rtable entries are laid out in the 1-D data space. The … WebIn a three-dimensional array, each dimension having two elements, the array element order would be (1,1,1), (2, 1, 1), (1, 2, 1), (2, 2, 1), (1, 1, 2), (2, 1, 2), (1, 2, 2), (2, 2, 2).
