I am pleased to announce the release of mds-utils 2.1.0 <http://www.micheledestefano.joomlafree.it/en/mds-utils.html>. Features summary --------------------------- MDS-UTILS provides: 1. a tool for detecting machine endianity. 2. utilities for the Boost uBLAS library. Amongst them, some type traits for detecting different uBLAS matrix types. 3. some useful classes that allow to treat the old C FILE pointer as a C++ stream. 4. C++ wrappers of the main Python objects, independent of those in Boost Python. Wrappers are provided also for NumPy arrays. 5. C++ classes that help on treating Python file objects as C++ streams. 6. a review and refactor of the indexing support in Python extensions. Now access in write mode is supported too. 7. new C++ *to-Python* and *from-Python* converters for some *Boost uBlas* objects and for standard Python objects. These converters do not depend on Boost Python. 8. a new sequence iterator that is able to wrap Python sequences and allows also to modify them. This feature does not depend on Boost.Python. 9. the NDArrayIterator class, that wraps the Numpy C-API iterator and allows easy management of conversions to/from Numpy arrays. 10. some SWIG interface files, for easy integration with SWIG extensions for Python. Each class is a well-documented, small, easy to use and it should never be too difficult to learn to use it. A large percentage of this library makes a heavy usage of the Boost C++ libraries <http://www.boost.org/>: so, they must be installed on the system. It is assumed that the user is familiar with them.
