Today I finished editing the second edition of our book titled Numerical Methods in Practice ("Numeeriset menetelmät käytännössä", written in Finnish). The book is available on the web in PDF format at the address

http://www.csc.fi/oppaat/num.kayt/

There are two PDF files: the whole book, about 6.3 MB, and the introductory chapters plus appendixes, about 800 kB. There are 415 pages in the book, only 29 more than in the first edition. New topics include wavelets, the Fourier transform, and adaptive FEM. The printed version will appear this Fall.
