% Generate a 3X4 integer data matrix

A = randi(100,)

% Perform matrix permutation on the matrix

A = A'

% Replace and then sort in row order

A = sort(A,1)

% Finally find the average of each column< /p>

m = mean(A)

The running results are as follows

A =

44 80 45 76

39 19 65 28

77 49 71 68

A =

44 39 77

80 19 49

45 65 71

76 28 68

A =

44 19 49

45 28 68

76 39 71

80 65 77

m =

61.2500 37.7500 66.2500
