Answer to my self. I see in lapack manual pages
that all arguments are marked as input, input/output and
output. So all arguments that are 'input' aren't modified.
Quoting Dima Sorkin:
Does DTRCON modify any entry in its input matrix "A" ?
It is not mentioned in it's manual page that it makes
any modification to "A", but I ask to be sure.
Thank you, regards,
