The arrays are not specifically designed to deal with image data, although image and graphic libraries could make use of them. It's not clear whether this is the case for GIL having never used it myself. Looking through GIL's tutorial though and ignoring image specific terminology there does appear to be some similarity.
The main difference between the math arrays in the library and uBLAS is that they're defined as fixed-size arrays. The other differences at the moment is only dense arrays and operations on them are available, and no algebra has been implemented.
AFAIK there are fixed size arrays for boost ublas in the most recent version(s?), but I am not entirely sure.
I guess the question I am asking is when should I use your arrays over UBLAS or GIL? Can your arrays be integrated?
The storage type of uBLAS arrays, as far as I'm aware, is always a linear array of consecutive memory locations where the type implements special purpose iterators, etc. As such I would presume integration is not possible with that library, however, I've never tried. Whether integration with GIL is possible is also unknown.
What I really meant to say here is... The storage type of uBLAS arrays is always a linear array of consecutive memory locations and can be a std::vector, or one of the storage types supplied by the library. As such I would presume a 1-dimensional array from the library could be used as the storage type but I don't see any benefit in using it that way, and in any case I've not tried. etc,. Regards Brian
