Information about my e-books
Here, you can find supporting
information for the e-books that I have prepared. The books
themselves are published with Leanpub, where they can be
downloaded (see my author page).
You decide the price: there is a suggested price, but you
are also allowed to download them for free, no problem.
Preparing these books, the Matlab
software, and maintaining this website, is done in my
own time. So, the more money I can collect with book sales,
the more time I can invest in these activities. You need to
create an account at Leanpub, with your email address. The
good thing is that I can see how many people have downloaded
my books, and you get a message whenever I publish a new
version. Furthermore, you can comment on the book at the
At this moment, the following books are on offer:

Why (free) e-books?
First and foremost because I want
to make this information available to as broad an audience
as possible. Furthermore, an e-book is more environment
friendly: you can read it from a pc, e-reader or tablet, or
you can print the specific parts you would like to read, and
I can easily keep the contents up-to-date. I now publish it
with Leanpub, which offers people the option to pay for the
book (though they can also set the price to 0$). I get a
fair share from the proceedings, I keep all copyrights, and
I can update the books whenever I like. It does not get any
Why the PDF format?
Because that is easiest to do with
LaTeX, and it allows you to print (parts of) it yourself.
PDF also offers the possibility to work with hyperlinks in
the document, which helps the reader navigate through the
text. Let me know if you would like to see a different
format (such as a dedicated e-book format). If I receive
enough requests, I may be tempted to dive into this matter.
How often do you update the books?
Difficult to say; it also depends
on how many people pay for the e-books (I mostly write them
in my own time). When I spot clear errors, I will correct
them ASAP. Further, I expect to add new literature with some
regularity. In any case, I will keep a version log to
clarify what changes I made in each new version. The PhD
thesis will certainly not be updated anymore.
