Method on @infsup: inv (A)

Compute the inverse of the square matrix A.

Accuracy: The result is a valid enclosure.

inv (infsup ([2, 1, 1; 0, 1, 0; 1, 0, 0]))
  ⇒ ans = 3×3 interval matrix
     [0]    [0]    [1]
     [0]    [1]    [0]
     [1]   [-1]   [-2]
inv (infsup ([1, 2, 3; 4, 0, 6; 0, 0, 1]))
  ⇒ ans = 3×3 interval matrix
       [0]     [0.25]    [-1.5]
     [0.5]   [-0.125]   [-0.75]
       [0]        [0]       [1]
