Numerous readers of the second edition have notified me about misprints and
possible improvements of the text and the associated computer codes. The
resulting modifications have been incorporated in this new edition and its
accompanying software.
The major change between the second and third editions, however, is
caused by the new implementation of Numerical Python, now called numpy.
The new numpy package encourages a slightly different syntax compared to
the old Numeric implementation, which was used in the previous editions.
Since Numerical Python functionality appears in a lot of places in the book,
there are hence a huge number of updates to the new suggested numpy syntax,
especially in Chapters 4, 9, and 10.
