Example: To create a matrix and calculates the mean of each column.

% create the 3x3 matrix as 
n=[1,2,3;3,2,1;4,5,1] 

v=mean(n)

Output:

n =

     1     2     3
     3     2     1
     4     5     1


v =

    2.6667    3.0000    1.6667

Explanation:

• 2.6667, 3.0000 and 1.6667 is the mean value of the first, second and third column elements respectively.
