Hi
I am using the linear algebra header for one of my simulations. I want to invert a matrix and i tried using the gsl LU invert function for real numbers.
Whatever be the order of the square matrix , only the last two rows of the output has valid
numbers. the rest of it is either "nan" or "inf" which is wrong.
Am I using the function in a wrong manner? I have been using a permutation
matrix which is the identity matrix. do i need to change it?

I had some trouble with LU also. I'm not sure if there is a GSL bug or
I'm doing something wrong. I have had success with the SVD method. So,
I'd suggest giving that a try.
