It is assumed that there are calculated values according to the each iterations.

if..

by for loop,

1st  ->   31  14                     min = 14
2nd  ->   31  14  61                 min = 14 
3rd  ->   31  14  61  74             min = 14 
4th  ->   31  14  61  74  10         min = 10
5th  ->   31  14  61  74  10  2      min = 2
6th  ->   31  14  61  74  10  2  50  min = 2

If the values are not less than 2 after 6th, it will be decided as minimum value 2.

How to write code that way?

The description is not clear. Prefer to post the current code or provide the input data in valid Matlab syntax. Currently the readers have to guess too many details.

Actually all you need is the min() command and perhaps an if to consider "If the values are not less than 2 after 6th, it will be decided as minimum value 2". Please try it.

I suppose this is a homework and you're not allowed to use in-built functions like min. If so, you have to read about

matrix indexing
and how loop control statements work
and then how conditional statements work

if you get an idea of how these things work, you can easily write a program. If you have problems or questions while you're at it, just write a comment here. Good luck!
