Test Status Code Input and Output
1   Fail
x = [1 2 3]; w = [10 15 20]; y_correct = 100/3; assert(isequal(weighted_average(x,w),y_correct))

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 weighted_average (line 2) a=x*w; Error in Test1 (line 4) assert(isequal(weighted_average(x,w),y_correct))

2   Fail
x = [0 -2 3]; w = [10 0 10]; y_correct = 10; assert(isequal(weighted_average(x,w),y_correct))
