Hi,
please can you help me with Lapack implementation. I have used zgetrf for LU decomposition but the info (error integer) is not zero - info=2. I understand that when info > 0 than the matrix I send the Lapack to decompose is singular. But the value of info, what does it mean? Is it a line which is linearly dependent? Or something other?
I need to find the error in matrix and this is a quite big matrix, it would be a great help to know more from the Lapack.
Thanks
