USE THE SUM FUNCTION

Problem 7. Write a one-line MATLAB expression that evaluates to a logical 1 if the sum of a and b is greater than N, unless b is less than 0. Otherwise the statement should evaluate to a logical 0. Write your code so that it shows the output for the following cases: a, b, c, a-5, b = 4, N = 7 a=5, b = 4, N = 11 a-5, b =-1,N=2
