Hi everyone,
I have written a header for runtime-flexible multi-dimensional views and arrays and would love to get comments and feedback from the boost community:
tutorial code : http://tinyurl.com/7hdldc9 main website : http://www.andres.sc/marray.html doxygen reference doc: http://www.andres.sc/marray/doc/index.html git repository : https://github.com/bjoern-andres/marray tech report : http://arxiv.org/pdf/1008.2909v1
Unlike in Boost.MultiArray, the dimension of arrays is not a template parameter in Marray. Other features include
- runtime-flexible dimension, shape, size and indexing order (first or last coordinate major order) - arithmetic operators with automatic type promotion and expression templates. - access to entries via coordinates, scalar indices and STL-compliant random access iterators. - derived classes for matrices and vectors - support of exchangeable STL-compliant allocators.
Thanks for your consideration Bjoern
This sounds somewhat like: http://svn.boost.org/svn/boost/sandbox/variadic_templates/sandbox/stepper/bo... with these several extra features:
- arithmetic operators with automatic type promotion and expression templates. - access to entries via coordinates, scalar indices and STL-compliant random access iterators. - derived classes for matrices and vectors - support of exchangeable STL-compliant allocators.
However, array_dyn has the ability to permute its axes (an array transpose is just a reverse of the axes). Demonstration of an application of such a permutation of axes (well, actually, a rotation of the axes) is here: http://svn.boost.org/svn/boost/sandbox/variadic_templates/sandbox/stepper/li... and a more useful example is here: http://svn.boost.org/svn/boost/sandbox/variadic_templates/sandbox/stepper/li... That last array_dyn code was made in response to post: http://article.gmane.org/gmane.comp.lib.boost.user/68017/match=multi+array+p... -regards, Larry
