comfort-array: Arrays where the index type is a function of the shape type

[ bsd3, data-structures, library ] [ Propose Tags ]

Arrays from the basic array package are already very powerful compared with arrays in other languages. They may have any number of dimensions, are type safe and defined in a uniform way using the Ix class with free choice of the lower bounds (0, 1, or whatever you like).

This package goes one step further: The shape and the index type are different, but the index type is a type function of the shape type. This offers much more flexibility and type safety.

Some examples are:

The lapack package defines even more fancy shapes like tall rectangular matrices, triangular matrices and banded matrices.
