By changing elements of rows and columns
In this method, we are simply changing the elements of particular rows and columns in the specified rows and columns respectively.
Example 1:
Matlab
% MATLAB code for 2*2 matrix. its first and % second elements of the first column are being swapped A = [5 10 15 20] % Swapping the first and second elements of the first column A([1 2]) = A([2 1]) |
Output:
A = 5 10 15 20 A = 15 10 5 20
Example 2:
Matlab
% MATLAB code for 3*3 matrix. The second and third elements of the first % column are being swapped. And later, the first and second elements % of the second column of the swapped matrix are swapped again. A = [5 10 15 20 25 30 35 40 45] % Swapping the second and third elements of the first column A([2 3]) = A([3 2]) % Swapping the first and second elements of the second column % of the above swapped matrix A([4 5]) = A([5 4]) |
Output:
A = 5 10 15 20 25 30 35 40 45 A = 5 10 15 35 25 30 20 40 45 A = 5 25 15 35 10 30 20 40 45
