There is Chapter 2.3 in Numerical Recipes in C:
http://www.library.cornell.edu/nr/cbookcpdf.html

Also note the following chapters that discuss special matrices and
their inversion. If your matrix has a special form, inverting it might
be possible in a faster manner than with general LU decomposition.
