If A is a multidimensional array,then sort(A) operates along the first array dimensionwhose form size does not equal 1, treating the elements as vectors.

B = sort(A,dim) returnsthe sorted elements of A along dimension dim.For example, if A is a matrix, then sort(A,2) sortsthe elements of each row.

B = sort(___,direction) returnssorted elements of A in the order specified by direction usingany of the previous syntaxes. "ascend" indicatesascending order (the default) & "descend" indicatesdescending order.

B = sort(___,Name,Value) specifiesadditional parameters for sorting. For example, sort(A,"ComparisonMethod","abs") sortsthe elements of A by magnitude.

=sort(___) also returns a collection of indexvectors for any of the previous syntaxes. I isthe same size as A và describes the arrangementof the elements of A into B alongthe sorted dimension. For example, if A is a vector,then B = A(I).

Starting in R2017a, you can create string arrays using double quotes, and sort them using the sort function. Sort strings in each column of a string array according to lớn Unicode® dictionary order.

Create an array of datetime values and sort them in ascending order, that is, from the earliest lớn the latest calendar date.

B lists the sorted dates and I contains the corresponding indices of A.

Access the sorted elements from the original array directly by using the index array I.

Sort the elements of a complex vector by their real parts. By default, the sort function sorts complex values by their magnitude, & breaks ties using phase angles. Specify the value of "ComparisonMethod" as "real" khổng lồ instead sort complex values by their real parts. For elements with equal real parts, sort breaks the tie based on their imaginary parts.

B = 1×5 complex 0.0000 - 1.0000i 0.0000 + 0.0000i 0.0000 + 1.0000i 1.0000 + 2.0000i 3.0000 + 1.0000i

If A is a scalar, then sort(A) returns A.

If A is complex, then by default, sort sortsthe elements by magnitude. If more than one element has equal magnitude,then the elements are sorted by phase angle on the interval (−π,π>.

If A is a string array, then sort reordersthe elements of the array, but does not reorder characters withinthe strings.

If A is a categorical array, then the sorting order is based on the category order returned by categories(A).

Data Types: double | single | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char | string | cell | categorical | datetime | durationComplex Number Support: Yes

Dimension to lớn operate along, specified as a positive integerscalar. If no value is specified, then the default is the first arraydimension whose form size does not equal 1.



sort returns A if dim isgreater than ndims(A). Dim isnot supported when A is a cell array, that is, sort onlyoperates along the first array dimension whose size does not equal1.

Data Types: double | single | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Sorting direction, specified as "ascend" or "descend". Direction isnot supported when A is a cell array, that is, sort onlysorts in ascending order.

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name & Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name và value, and enclose Name in quotes.

Example: sort(A,"MissingPlacement","last")

Placement of missing values (NaN, NaT, ,and missing) specified as the comma-separated pairconsisting of "MissingPlacement" & one of thefollowing:

"auto" — Missing elementsare placed last for ascending order and first for descending order.

"first" — Missing elementsare placed first.

"last" — Missing elementsare placed last.

Element comparison method, specified as the comma-separatedpair consisting of "ComparisonMethod" và one ofthe following:

"auto" — Sort A by real(A) when A isreal, & sort by abs(A) when A iscomplex.

"real" — Sort A by real(A) when A isreal or complex. If A has elements with equal realparts, then use imag(A) to break ties.

"abs" — Sort A by abs(A) when A isreal or complex. If A has elements with equal magnitude,then use angle(A) in the interval (-π,π>to break ties.
