How do I create a function where output S has the rows as input N

I am trying to create a function where the output S shows selected statistics of input N. I need output S to have the same number of rows as input N. The first column of S has to contain the mean values of the corresponding rows in N. (I will add median and minimum values later.)

Right now my result is 2.5 (the mean value of the first row in N). However I want it to keep going and calculate the mean value of row two(5.5), three(9.5) etc.

N =[1 2 3 4;4 5 6 7;8 9 10 11]

my function:

 function [S]=simple_stats(N)
     S=mean(N(1:1:1,1:1:end));
      end

Thank you!

TMW already wrote the function for you...

>> N =[1 2 3 4;4 5 6 7;8 9 10 11];
>> S=mean(N,2)
S =
                     2.5
                     5.5
                     9.5

The various other functions have similar DIM arguments; read the documentation/help.

Thank you. Much simpler than my code
