## @defmethodx {@@infsup} reshape (@var{X}, [@var{M} @var{N}])
##
## Return an interval matrix with the specified dimensions (M, N) whose
## elements are taken from the interval matrix @var{A}. The elements of the
## matrix are accessed in column-major order (like Fortran arrays are stored).
##
## Note that the total number of elements in the original matrix
## (@code{prod (size (@var{A}))}) must match the total number of elements in
## the new matrix (@code{prod ([@var{M} @var{N}])}).
##
## @example
## @group
## reshape (infsup (1 : 6), 2, 3)
## @result{} ans = 2×3 interval matrix
## [1] [3] [5]
## [2] [4] [6]
## @end group
