Given a matrix, return the first eigen value

For example: x = magic(5)

   17   24    1    8   15
   23    5    7   14   16
    4    6   13   20   22
   10   12   19   21    3

How is it possible that the same matrix x in test 2 and test3 give different results? I guess you copy in the test 3 the wrong matrix?

Impossible to understand the tests

Too much variation on how many digits of precision you want

Now should be ok. Sorry but it is my first problem published.
For any question write me.
