How does the backslash operator work? What does it do?
For full matrices, pseudocode describing the algorithm can be found here: http://www.mathworks.com/support/solutions/data/22317.shtml For sparse matrices, the URL is: http://www.mathworks.com/support/solutions/da ta/21798.shtml Also for sparse matrices, you can turn on monitoring routines that show you so me of the steps.
