Documentation​

Swaps the rows and columns of a matrix represented by a vector of vectors.

Examples​

Transpose a vector of vectors.​

      matrix = [[0, 1, 2], [3, 4, 5], [6, 7, 8]]
      # +---+---+---+
      # | 0 | 1 | 2 |
      # +---+---+---+
      # | 3 | 4 | 5 |
      # +---+---+---+
      # | 6 | 7 | 8 |
      # +---+---+---+

      transposed = [[0, 3, 6], [1, 4, 7], [2, 5, 8]]
      # +---+---+---+
      # | 0 | 3 | 6 |
      # +---+---+---+
      # | 1 | 4 | 7 |
      # +---+---+---+
      # | 2 | 5 | 8 |
      # +---+---+---+

      matrix.transposed == transposed
      # => True
