Test Status Code Input and Output
1   Fail
A = [2 3; 3 4]; b = [23; 32]; x_correct = [4;5]; assert(isequal(solveSimul(A,b),x_correct))

b = 23 32

Error using * Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'. Error in solveSimul (line 3) x=inv(A)*b Error in Test1 (line 3) assert(isequal(solveSimul(A,b),x_correct))

2   Fail
A = [2 3; 3 4]; b = [23; 36]; x_correct = [16;-3]; assert(isequal(solveSimul(A,b),x_correct))

b = 23 36

Error using * Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'. Error in solveSimul (line 3) x=inv(A)*b Error in Test2 (line 3) assert(isequal(solveSimul(A,b),x_correct))

3   Fail
