[Blitz-support] Fast Array resize

[Bela B. <ba...@ph...>]

Hi,

I have a situation where I need to resize an array (rank 7) *very*  
often, where the overall number of items stays fixed and the extents  
get shuffled around (I'm rearranging large tensors). I end up  
spending a significant amount of CPU time in the resize() function.  
If I understand the source code of Blitz++ correctly, it will  
allocate a new array for every resize, even if that would actually be  
unnecessary in my situation.

Is there any way of avoiding this without modifying the Blitz source  
code - or if not, does anyone have an idea how I could modify this  
behaviour without having to get acquainted with the Blitz internals  
too much?

Thanks,
Bela
