Detailed explanation of the usage of sort function in Matlab_javascript skills

(1)B=sort(A) Sort the one-dimensional or two-dimensional array in ascending order and return the sorted array. When A is two-dimensional, sort each column of the array.

eg: A=[1,5,3], then sort(A)=[1,3,5]

A=[1,5,3;2,4,1], then sort(A)=[1,4,1;2,5,3]

(2)B=sort(A,dim), sort the array in ascending order in the specified direction,

dim =1 means sorting each column, and dim=2 means sorting each row.

(3)B=sort(A,dim,mode), mode is the specified sorting mode. When the mode is "ascend", the ascending order is performed. When the mode is "descend", the descending order is performed.

(4)[B,I]=sort(A,...), I is the row position or column position of the returned sorted element in the original array.

Some examples:

>> A=[3 4 2;1 5 3;4 7 1]

A =

3 4 2
1 5 3
4 7 1

>> A(:)

ans =

3
1
4
4
5
7
2
3
1

>> min(A(:))

ans =

1

>> max(A(:))

ans =

7

>> A

A =

3 4 2
1 5 3
4 7 1

>> sort(A)

ans =

1 4 1
3 5 2
4 7 3

>> A

A =

3 4 2
1 5 3
4 7 1

>> sort(A(:))

ans =

1
1
2
3
3
4
4
5
7

>> sort(A,1)

ans =

1 4 1
3 5 2
4 7 3

>> sort(A,2)

ans =

2 3 4
1 3 5
1 4 7

>> sort(A,1,"descend")
??? sort(A,1,"descend")

Error: Missing variable or function.

>> sort(A,1,'descend')

ans =

4 7 3
3 5 2
1 4 1

>> [B,I]=sort(A)

B =

1 4 1
3 5 2
4 7 3

I =

2 1 3
1 2 1
3 3 2
