在 MATLAB Online 中打开

d=[100 200 300; 
   250 350 450; 
   810 550 600; 
   500 700 400]
v=[1 1 1 1]

d has 4 rows and v has 4 elements.

If d's all of the elements of any row are less than 800, v (row) must be equal to 5. But this process must continue until any element of any row is greater than 800.

Example:

d(1,:)<800 so v(1)=5

d(2,:)<800 so v(2)=5

d(3,:), all of them not less than 800. So v(3)=1

d(4,:)<800. But v(4) will not be changed. Because we find a value which is greater than 800 at row 3.

How can i achieve this problem?

Thanks,
