Return a copy of x with the elements arranged in increasing order.
sort orders the elements within columns
sort ([1, 2; 2, 3; 3, 1]) ⇒ 1 1 2 2 3 3
If the optional argument dim is given, then the matrix is sorted
along the dimension defined by dim. The optional argument
defines the order in which the values will be sorted. Valid values of
sort 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
For equal elements, the indices are such that equal elements are listed in the order in which they appeared in the original list.
Sorting of complex entries is done first by magnitude (
and for any ties by phase angle (
angle (z)). For example:
sort ([1+i; 1; 1-i]) ⇒ 1 + 0i 1 - 1i 1 + 1i
NaN values are treated as being greater than any other value and are sorted to the end of the list.
sort function may also be used to sort strings and cell arrays
of strings, in which case ASCII dictionary order (uppercase ’A’ precedes
lowercase ’a’) of the strings is used.
The algorithm used in
sort is optimized for the sorting of partially
