Let me guess. The other rows contain really small elements.

Print out the submatrix that you get by leaving out the first row. Now are the rows still zero?

I hope you see that that is not possible.

I attach the program to invert the matrix with the matrix. As you see, is a matrix with possitive less than 1 elements in the diagonal and negative elements in the rest of the matrix. Do you get the same result?
