June 2012:

There seems to be some inaccuracy in the paper for one column.
The Matlab files gives somewhat different results, see Master thesis of Roald B. Leer.
The difference is mainly in the location of the horizontal line in Fig. 3.2.
The difference is possibly because the feed stage should be moved from 20 to 21.

For two columns, the results in the paper are the same as with the Matlab files.
