Knuth applies ``the standard technique of Gaussian elimination''
to convert a system of equations to the diagonal form. The complexity
of this method is x^3. Is it possible ( practically, i.e., not
using tricks of the kind of Strassen's fast matrix multiplication,
http://mathworld.wolfram.com/StrassenFormulas.html ) to gain
a significant speed-up? Sorry for a silly question, but I'm not
``au courant'' with respect to recent advances in numerical
