— Function File: [s, i] = fsort (x)

Return a copy of the fixed point variable x with the elements arranged in increasing order. For matrices, fsort orders the elements in each column.

For example,

          fsort (fixed(4,0,[1, 2; 2, 3; 3, 1]))
            1  1
          2  2
          3  3

The fsort function may also be used to produce a matrix containing the original row indices of the elements in the sorted matrix. For example,

          [s, i] = sort ([1, 2; 2, 3; 3, 1])
           s = 1  1
          2  2
          3  3
           i = 1  3
          2  1
          3  2
