[Help-gsl] linear algebra doubt

[Adhithya Ravichandran]

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?

Adhithya
