I pushed a simple change to the web repository

http://hg.octave.org/web-octave/rev/cb5ec7b6c582

I don't have jekyll installed at the moment, someone else will have to build and push this change to the web site.

Dear all,

the description


x = A \ b     # Solve the system  Ax = b  by inverting A


on the website is not correct. The matrix is not inverted, rather the LU factorization is computed. Inverting matrices for solving linear systems is generally bad.
