write test cases for a code that finds an average of ten numbers in matlab

main.m
% Test Case 1: Test with an array of positive numbers
input1 = [2, 4, 6, 8, 10, 12, 14, 16, 18, 20];
expectedOutput1 = 11;
assert(isequal(calcAvg(input1), expectedOutput1), 'Test Case 1 Failed');

% Test Case 2: Test with an array of negative numbers
input2 = [-2, -4, -6, -8, -10, -12, -14, -16, -18, -20];
expectedOutput2 = -11;
assert(isequal(calcAvg(input2), expectedOutput2), 'Test Case 2 Failed');

% Test Case 3: Test with an array with a mix of positive and negative numbers
input3 = [-2, 4, 6, -8, 10, -12, 14, -16, 18, -20];
expectedOutput3 = -2;
assert(isequal(calcAvg(input3), expectedOutput3), 'Test Case 3 Failed');
