matlab sortrows

The sortrows function in MATLAB is used to sort a matrix or table based on one or more columns. The syntax for the function is:

B = sortrows(A, cols)

where A is the matrix or table to be sorted, cols is a vector of column indices specifying the order of sorting. For example, if cols = [3 1], the matrix will be sorted first by the values in column 3, and then by the values in column 1.

The output B is a sorted version of A. If A is a matrix, B is also a matrix. If A is a table, B is a table with the same variable names and properties as A.

Here's an example of using sortrows to sort a matrix:

A = [5 4 3; 2 1 6; 7 8 9];
B = sortrows(A, [2 1]);

In this case, the matrix A is sorted first by column 2, and then by column 1. The result B is:

B = 
   2   1   6
   5   4   3
   7   8   9
