I have a function that input a matrix and a vector
function s= solve(A, b)
for i=1:N
s(i)= something
end
end
I want it to retunr the whole vector, like if disp(Solve(something)) would output a vector !
Can I use the return command here ?

That code outline already returns a whole vector. For example,
disp(mysolve(magic(6), [6;5;5;3;2;1]))
385 347 381 439 455 435
function s = mysolve(A,b)
for i = 1 : size(A,1)
s(i) = dot(A(i,:), b);
end
end

First line, N=size()
Is the order of filling the vector relevant?

You take size(b, 2) which is the number of columns in b. But suppose you were passed a column vector then the number of columns would be 1.
