So, there is no communication between the threads about the step size,
and each thread can choose their own step size?
Thanks,

Hei,
I am currently using the odeint-solver for calculating the right hand
side of a non-linear equation. For speeding up the calculation of the
right hand side, I decided to test the MPI-implementation. Now, after I
would prefer to keep the code backwards compatible, I did not want to
replace

I'm just guessing. Why don't you put this through its paces, then
contribute revised documentation and tests for the new library?
Done.
Dear Nicolas,
sorry for the late reply. Some other projects try to keep me busy.
First, I'd like to mention that in German-speaking countries, EDV
is a very common acronym for Elektronische Datenverarbeitung
(electronic data processing), hence the library name might be
somewhat confusing.
Hi Thomas,
some time ago I was in the very same situation
that I needed an iterator of tuples - or a tuple
of iterators, which virtually is the same IMO.
My solution then was to extend tuple functionality,
i.e. to add everything that a good iterator requires,
such as dereference,

I need to split a string into tokens, and split the
resulting tokens again in a second pass. Currently,
I do this with boost::tokenizer initialized

The problem is that all the quote characters are

Hi,
as mentioned in the docs, it is necessary to tell MS VC++
all template parameters of an iterator_adaptor *explicitly*.
Unfortunately, it seems one cannot do that for a permutation_iterator,
since permutation_iterator_generator just takes ElementIterator
and IndexIterator as its template
There has been some out-of-list discussion about this, and some work is
being done. There's a PP based tuple implementation (mostly written by
Joel) in Spirit's CVS that conforms to the Tuple speicification in the TR.
Where is it?
Do you refer to the files under

The fundamental problem is that it's inconvenient to iterate through a

Iterating is again conceptually simple -- just increment an index.
But the fact that get is a template implies the index must be a
Dear all,
today I imported another set of files to Sandbox CVS,
this time something I'd like to call 'tupples' (yes, two p's).

You all know Boost.Tuples (with one 'p'), right?
Well, tupples is almost the same, only different.
There are two major differences:

Dear all,
I would like to announce that I finally imported the first set
of Boost.View classes to the Boost-Sandbox CVS.
+ What is it?
A view is a light-weight, immutable decorator to some existing data.
Usually, it will provide the same interface as a STL container.
In much the same way as

No. A view is not mutable; sometimes the
Dear all,
just a minor issue for the upcoming(?) lexical_cast in 1.30.0:
lexical_castbool( true ) returns false,
since std::ios::boolalpha is not set by default.
How about changing this?
