While testing the linear algebra functions provided in gsl I came across
the following.

With appropriate setup the call to,

gsl_linalg_LU_invert(squareMatrix, perm, squareInverse);

gave the inverse of the transpose of squareMatrix. I verified this using
octave. Note that squareMatrix is a simple 3x3 matrix of Gaussian variates.
Is this the expected behaviour?
