### Test Suite

Test Status Code Input and Output
1   Pass
x = ones(2); y_correct = 4; assert(isequal(sumDiagonalElements(x),y_correct))

y = 4

2   Fail
x = ones(3); y_correct = 5; assert(isequal(sumDiagonalElements(x),y_correct))

y = 6

Index in position 1 exceeds array bounds (must not exceed 1). Error in sumDiagonalElements (line 5) y=y-y(t(1),t(2)) Error in Test2 (line 3) assert(isequal(sumDiagonalElements(x),y_correct))

3   Pass
x = magic(8); y_correct = 520; assert(isequal(sumDiagonalElements(x),y_correct))

y = 520

4   Fail
x = magic(9); y_correct = 697; assert(isequal(sumDiagonalElements(x),y_correct))

y = 738

Index in position 1 exceeds array bounds (must not exceed 1). Error in sumDiagonalElements (line 5) y=y-y(t(1),t(2)) Error in Test4 (line 3) assert(isequal(sumDiagonalElements(x),y_correct))
