The file maps.zip in the containers directory in Boost's vault contains a library with classes for the development of multi-dimensional array applications. Also included are scalar and fixed-size vector and matrix class templates with an expression template implementation of operators. The multi-dimensional array's can be fixed-size statically or dynamically allocated, or dynamically allocated and resizeable. Vectors and matrices can be statically or dynamically allocated and written in block form. The notation follows that provided by the STL and other Boost libraries. The classes lack tests using Boost's test framework and the documentation is rather sparse. The intention would be to remedy both issues if interest is sufficient to warrant it. Regards Brian
