so the question i have is:

Write a single function that takes in a square integer matrix A and the scalars N and G, as well as a 2-value vector R indicating the inclusive range [R(1), R(2)] as inputs.

Has to return:

(1):average of the elements in the nth column

(2):value of the most occuring element

(3):the number of elements within a specified range R, inclusive of the edge values

(4):a Mx2 matrix, with each row containing two elements to represent the indicial position (i.e. row number, column number) of each appearance of the number G.

So far what i have:

(1)

Code:

if (N > size(A,2))
fprintf('N is out of range of columns');
else
for i = A(:, N)
A2 = A2 + i;
end
end
fprintf('A1 is %d, A2 is %d', A1, (A2/i));

and the rest im still doing them, dont think i can do 3 and 4 but 2 should be no problem... any pointers/tips would be great! thanks
