Test Status Code Input and Output
1   Pass
n=3; y=[1 0 1 0 1 0 1 0 1]; assert(isequal(X(n),y))

y = 1 0 1 0 1 0 1 0 1

2   Fail
n=4; y=[1 0 0 1 0 1 1 0 0 1 1 0 1 0 0 1]; assert(isequal(X(n),y))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in X (line 8) y((n+1)/2,(n+1)/2)=1 Error in Test2 (line 6) assert(isequal(X(n),y))

3   Pass
n=1; y=[1] assert(isequal(X(n),y))

y = 1 y = 1

4   Fail
n=2; y=[1 1;1 1] assert(isequal(X(n),y))

y = 1 1 1 1

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in X (line 8) y((n+1)/2,(n+1)/2)=1 Error in Test4 (line 3) assert(isequal(X(n),y))
