So figure out the third and fourth rows and you are done!

Actually, if you read your post you didn't ask for help. You stated that you had a need. I have needs as well, but I don't expect others to deal with them for me unless I actually ask.

Did you actually have a question about the problem that you'd like an answer to? Or are you looking for someone to code this for you?

Do you have a definition of the 'sign' of a row of a matrix? There
really isn't a common standard that would be universally applied (I
think I can get an idea of what you want from your example, but getting
an actual definition is the first step of solving a problem)
