Write a function called sum_rows that takes a matrix as input argument
(the function does not have to check the format of the input) and returns
a vector as an output argument. The elements of the vector are the
sums of the elements of the rows of the input matrix. Note that the built-in
MATLAB function sum returns the sum of the columns.

sum function get dim (dimension which summuation operate on it) as second arguments.
so just use :
a function :
function x=sum_(A)

Please do not do student homework assignments for them. This does not help the student, even if they seem grateful. All the student learns is they can use Answers as a way to do their homework for them. I would point out that the poster has posted two obvious homework assignment questions. (I closed the other.) If not discouraged, they will continue to post their entire assignments.
