A matlab question, can anybody help please

Write a MATLAB function that accepts two integer (i.e., whole) numbers as input, and returns
the sum of all the integers in between, including the two input variables.

I just don't get the concept of the question. Help is appreciated! :)

If your first integer is 3 and your second one is 6, your script has to return the result of 3 + 4 + 5 + 6
Not very hard, is it?

a = input('Give me an integer: ');
b = input('Give me another integer: ');
sum(a : b)
