Code Input and Output

1

Fail

%% M = 1; v = 7; d = 0; M2 = 7; assert(isequal(setDiagonal(M,v,d),M2)); assert(isequal(setDiagonal(M,v),M2));

Error: Output argument "ans" (and maybe others) not assigned during call to "/users/msssytem8/setDiagonal.m>setDiagonal".

2

Fail

%% M = magic(5); v = 1:3; d = 2; M2 = M; M2([11,17,23]) = v; assert(isequal(setDiagonal(M,v,d),M2));

Error: Output argument "ans" (and maybe others) not assigned during call to "/users/msssytem8/setDiagonal.m>setDiagonal".

3

Fail

%% M = rand(6); v = [.2 -.2]; d = -4; M2 = M; M2([5,12]) = v; assert(isequal(setDiagonal(M,v,d),M2));

Error: Output argument "ans" (and maybe others) not assigned during call to "/users/msssytem8/setDiagonal.m>setDiagonal".
