### Test Suite

Test Status Code Input and Output
1   Fail
n = 1; mat=[1 1]; ok = 1; assert(isequal(FillWithOnes(n,mat),ok))

ans = 1 1

Assertion failed.

2   Fail
n = 2; mat=[1 2; 2 1]; ok = [0 1; 1 0]; assert(isequal(FillWithOnes(n,mat),ok))

ans = 1 2 ans = 2 1

Assertion failed.

3   Fail
n=3; mat=[1 3; 3 2; 3 3]; ok = [0 0 1; 0 0 0; 0 1 1]; assert(isequal(FillWithOnes(n,mat),ok))

ans = 1 3 ans = 3 2 ans = 3 3

Assertion failed.

4   Fail
n=4; mat=[1 3; 3 2; 3 3]; ok = [0 0 1 0; 0 0 0 0; 0 1 1 0; 0 0 0 0]; assert(isequal(FillWithOnes(n,mat),ok))

ans = 1 3 ans = 3 2 ans = 3 3

Index in position 1 exceeds array bounds (must not exceed 3). Error in FillWithOnes (line 5) mat(i,:) Error in Test4 (line 4) assert(isequal(FillWithOnes(n,mat),ok))
