Dear Prabhanjan,

you need to know some linear algebra and m-file programming, at least. For 
instance, can you implement the standard conjugate gradient method in GNU 
Octave (algorithm 6.18 of the book?). Then, cloning GNU Octave primary 
archive and compile it from the sources. Have you already tried? Finally, 
can you apply the patch developed by Cristiano last year and understand 
his work?

About the book, at least four additional functions are missing in GNU 
Octave. Therefore, you need the chapters relevant for these functions.
