I need to write a function in which you enter 2 inputs, and the output is the sum of the integers between those numbers. for example, if x=(1,4) y should equal (1+2+3+4) (y=10) It should give the same output when x=(4,1). This should be able to be done using a forloop, but im not sure how to do it.

The 'ceil' and 'floor' are used here in case the inputs are not integers.
function s = sumintegers(a,b)
if a <= b
s = sum(ceil(a):floor(b));
else
s = sum(ceil(b):floor(a));
end
return
