### Test Suite

Test Status Code Input and Output
1   Fail
M = rand(4); a = [4 3 2 1]; b = [1 2 3 4]; v_correct = M([4 7 10 13]); assert(isequal(twoIndex(M,a,b),v_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "twoIndex".)

2   Fail
M = rand(4); a = [3 3 1 3]; b = [1 1 3 1]; v_correct = M([3 3 9 3]); assert(isequal(twoIndex(M,a,b),v_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "twoIndex".)

3   Fail
M = rand(100); [a,b] = size(M); v_correct = M(end); assert(isequal(twoIndex(M,a,b),v_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "twoIndex".)

4   Fail
M = rand(100); a = []; b = []; assert(isempty(twoIndex(M,a,b)))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "twoIndex".)

5   Fail
M = 1; a = [1 1 1 1 1]; b = [1 1 1 1 1]; v_correct = [1 1 1 1 1]; assert(isequal(twoIndex(M,a,b),v_correct))

Error in solution: Line: 5 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "twoIndex".)
