### Test Suite

Test Status Code Input and Output
1   Pass
x = [1 2 3 4 5 6 7]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

2   Fail
x = [2 2 2 2 2 2]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

Error using split_it (line 6) Index exceeds matrix dimensions.

3   Fail
x = [2 5 4 5 4]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

Error using split_it (line 6) Index exceeds matrix dimensions.

4   Fail
x = [1 3 1 1 9 7]; xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

Error using split_it (line 6) Index exceeds matrix dimensions.

5   Fail
x = primes(100); xi = split_it(x); assert(isequal(sum(x(xi)),sum(x)/2));

Error using VisibleTest5 (line 2) Output argument "xi" (and maybe others) not assigned during call to "split_it".
