I had information on these rather buried, and did not have a single example
of how to compute them. Now the first part of the chapter covers this much
more thoroughly.
Also added a section on plotting exponentials. Not sure I want to retain
it; it is a bit 'light'.
If you add a semi-colon to the end of the interact call
it hides the printing of the return function. This happens
because interact is both a function and a generator so it
can be a decorator.
I finally learned that the raw cells let you put latex directly
into the output. So now I have the appendix being created without
the [1] %%latex showing up in the output. Also wrote code to parse
the .tex file to make the Preface a chapter without numbering, so it
is now a proper preface, and not "chapter 0".
I have not touched the Windows generation tools, so PDF generation
in Windows is now broken. I don't think I care.
Some sections jumped from level 2 to level 4, for example.
Also played around with generating book to HTML. I like it, but
it needs some work. The Calico table of content generator cannot
deal with different headers with the same name, for example.
I want to go to HTML so I can use Bokeh to have interactive plots.
But that means no more PDF, because Bokeh will not export to
PDF.
Use of markdown was causing chapters to be merged together.
I made the change to markdown in some place in preparation for
IPython 3.0, but that turned out to be a bad idea (plus, 3.0
will automatically convert the headers correctly).
I was reusing the names for the state and measurement functions,
which made it impossible to run cells out of order, and was no
doubt confusing to the reader.
I think I finally arrived at a good ordering of material.
Started with implementing a linear problem just so we can
see how it differs from the linear KF, then added problems
step by step. Got rid of most of the poor performing filters.
I moved it more to the front as the pos vs velocity explanation
is difficult to understand if you do not already understand how
orthogonal or correlated measurements greatly increase precision.
Also various minor wording changes and fixes in other parts.
Position vs velocity confuses people, so I added a 2 position
reading example.
Fixed the Newtonian equation for jerk.
Changed indefinite integral in Newtonian equations to definite.
