randomMultidimensionalMatrix -- random multidimensional matrix

• Usage:

  randomMultidimensionalMatrix(d_1,...,d_n)

• Inputs:
  • (d_1,...,d_n), a sequence of positive integers.
• Optional inputs:
  • CoefficientRing => ..., default value ZZ
  • MaximalRank => ..., default value null
• Outputs:
  • a random multidimensional matrix of shape $d_1\times\cdots\times d_n$ over the ring specified by the option CoefficientRing (the default ring is ZZ).

i1 : randomMultidimensionalMatrix(2,4,3)

o1 = {{{8, 1, 3}, {7, 8, 3}, {3, 7, 8}, {8, 5, 7}}, {{8, 5, 2}, {3, 6, 3},

     {6, 8, 6}, {9, 3, 7}}}

o1 : 3-dimensional matrix of shape 2 x 4 x 3 over ZZ

i2 : randomMultidimensionalMatrix((2,2,3),CoefficientRing=>ZZ/101)

o2 = {{{-47, 38, 2}, {16, 22, 45}}, {{-34, -48, -47}, {47, 19, -16}}}
