Hi all,

Please help me out with this.I am new to numerical methods.

Please see the attached PDF document (I am not able to attach) or download the thesis form the link below.

http://www.iis.ee.ethz.ch/~laser/pdf...s/dip_lutz.pdf

The author uses the 'Thomas' algorithm to solve his PDE. I could not find it in NR in FOTRAN, which he refers to.

Also can someone please tell me, where can I find the central difference scheme used by the author of this thesis? Its really interesting for me (I am new to Numerical Analysis) . I am especially interested in the book this author referred with the specific notation and format. Can anyone identify it. The author again refers to the same book: NR in FORTRAN, The art of scientific Computing (2nd edition), CUP, 1992. Please tell me.

Thanks,

Jam

:( The link u gave did not work !

I'm guessing that if the author used the Thomas algorithm then he had used an implicit method (see http://www.library.cornell.edu/nr/bookcpdf/c19-2.pdf) to obtain a tridiagonal matrix.

This is covered by the routine tridag.

(sorry this reply is rather late to your post)
