Permutation matrix of a permutation list or Cycles object
PermutationMatrix[permv]
PermutationMatrix[pmat]
pm = PermutationMatrix[{4, 1, 3, 2}]
→ {{0, 0, 0, 1}, {1, 0, 0, 0}, {0, 0, 1, 0}, {0, 1, 0, 0}}pm = PermutationMatrix[Cycles[{{1, 4, 3}, {2, 5}}]]
→ {{0, 0, 0, 1, 0}, {0, 0, 0, 0, 1}, {1, 0, 0, 0, 0}, {0, 0, 1, 0, 0}, {0, 1, 0, 0, 0}}- TargetStructure — default Automatic
- WorkingPrecision — default Infinity
