dim(MultidimensionalMatrix) -- dimension of a multidimensional matrix

Synopsis

• Function: dim

• Usage:

  dim M

• Inputs:
  • M, a multidimensional matrix, an $n$-dimensional matrix of shape $k_1\times\cdots\times k_n$
• Outputs:
  • an integer, the integer $n$

Description

i1 : M = multidimensionalMatrix {{{0, 8, 3}, {7, 3, 2}, {2, 7, 0}, {4, 8, 4}}, {{0, 8, 1}, {3, 1, 0}, {4, 7, 4}, {0, 6, 9}}}

o1 = {{{0, 8, 3}, {7, 3, 2}, {2, 7, 0}, {4, 8, 4}}, {{0, 8, 1}, {3, 1, 0},
