4474f96263
removed lots of serialization in ODE
...
the only classes/interfaces for which serialization is really important in this package are the step interpolators. The reason for that is that the ContinuousOutputModel is explicitly serializable and contains step interpolators. This allows users to perform integration of any complex model and to save the result of the integration for all integration range by serializing a ContinuousOutputModel instance. This feature is a major one.

at integration start and is responsible for all time advancing stuff, including
step handlers and events handlers management.

More Serialization changes, mostly for ode and friends.
...
Unfortunately, had to leave some abstract base classes as Serializable, since they had no senible default construters. But left them with meaningless UIDs, to break anyone that doesn't override it.
Of course, if anyone has a better patch, I'm happy to implement it. At this point, the serialization changes for [math] should be almost done.

to prevent infinite loops if no convergence is reached
- objective function evaluations, for user information only
- objective function gradient/jacobian if the function is
differentiable, for user information only

Failed attempt to implement Strassen matrix multiplication on recursive layout as
...
described in Siddhartha Chatterjee, Alvin R. Lebeck, Praveen K. Patnala and Mithuna
Thottehodi paper "Recursive Array Layout and Fast Matrix Multiplication".
As of 2009-02-13, this implementation does not work! The padding at left and bottom
sides of the matrix should be cleared after some operations like scalerAdd and is not.
Also there is a limitation in the multiplication that can only process matrices with
sizes similar enough to have the same power of two number of tiles in all three
matrices A, B and C such that C = A*B. These parts have not been fixed since the
performance gain with respect to DenseRealMatrix are not very important, and the
numerical stability is poor.
This may well be due to a bad implementation.
This code has been put in the experimental directory for the record, putting it into
production would require solving all these issues.

Added a RealTransformer interface on top of cosine, sine and Hadamard transforms.
...
The Fourier transform cannot implement this interface since it produces complex results.
Improved error messages.

f8cc8e9d37
Added method to walk matrix entries with or without changing them in the
...
visitor design pattern sense. Two different orders can be used, row by row
of following internal storage. Internal order should be preferred when no
specific order is needed, because it will be more cache efficient.
