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 :
sum(A,2)
a function :
function x=sum_(A)
x=sum(A,2);
end

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.
