Test Status Code Input and Output
1   Pass
n = 2; y = [1 0;0 1]; assert(isequal(M_Const(n),y))

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

Unable to perform assignment because the size of the left side is 1-by-0 and the size of the right side is 1-by-2. Error in M_Const (line 7) y(k,(n/2)+1:-1:end)=(n/2):-1:1; Error in Test2 (line 6) assert(isequal(M_Const(n),y))

3   Fail
n = 6; y = [1 2 3 0 0 0 1 2 3 0 0 0 1 2 3 0 0 0 0 0 0 3 2 1 0 0 0 3 2 1 0 0 0 3 2 1]; assert(isequal(M_Const(n),y))

4   Fail
