Question

Please write in MATLAB code:

1. Write a function called myMin4 that will take in four numbers and returns the minimum value. You may NOT use the built-in min() function. Run the function for the following: myMin4(4, 8, 12, 15) myMin4(18, 9, 1, 6) myMin4(8, -2, 2, 10)

2.   Write a function called classAverage that takes in an array of numbers and returns the letter grade of the class average. The grade ranges are as follow: Average >90 = A 80<=Average <90 = B 70<=Average <80 = C 60<=Average <70 = D Average >60 = F

Run the function for the following class averages a) [70 86 95 79 80 78 80 90 66 89 89 100] b) [54 95 61 82 75 91 81 67 87 41 31 98] c) [65 25 46 72 74 55 68 74 80 30 69 67]

Answer 1

function minimum = myMin4(n1, n2, n3, n4)
    minimum = n1;
    if n2 < minimum
        minimum = n2;
    end
    if n3 < minimum
        minimum = n3;
    end
    if n4 < minimum
        minimum = n4;
    end
end

myMin4(4, 8, 12, 15) 
myMin4(18, 9, 1, 6) 
myMin4(8, -2, 2, 10)
