B = sort (A) sorts the duration array A in ascending order. If A is a matrix, sort (A) sorts each column of A in ascending order. For multidimensional arrays, mode (A) sorts along the first non-singleton dimension.

B = sort (A, dim) sorts along the dimension specified by dim.

B = sort (A, direction) also specifies the sorting direction, which can be either 'ascend' (default) or 'descend'.

B = sort (…, 'MissingPlacement', MP) specifies where to place the missing elements (<undefined>) returned in B with one of the following options specified in MP:

• 'auto', which is the default, places missing elements last for ascending sort and first for descending sort.
• 'first' places missing elements first.
• 'last' places missing elements last.

B = sort (…, 'ComparisonMethod', CM) specifies the comparison method for determining the order of elements returned in B with one of following options:

• 'auto', which is the default, sorts by real (A).
• 'real' sorts by real (A).
• 'abs' sorts by abs (A).

[B, index] = sort (A, …) also returns a sorting index containing the original indices of the elements in the sorted array. index is the same size as A and it comprises indexing vectors oriented along the operating dimensions.

• If A is a vector, then index contains the original linear indices of the elements in the sorted vector B such that B = A(index).
• If A is an $M\times N$ matrix and dim = 1, then index contains the original row indices of the elements in the sorted vector B such that for j = 1:N, B(:,j) = A(index(:,j),j).
