Hello Sebastien,

Ideally, you should be able to work with an array of doubles, rather than an array of pointers to double. I can create an multi_array with the dimensions you mention.

To answer your questions, multi_array uses a standard library allocator to allocate a contiguous block of memory in which to hold the array data. I'm afraid I do not know why you cannot exceed these limits.

I'm currently using multi_array to represent 3D matrices of doubles, I
was wondering which would be the best use since the array has to hold a
very large amount of data. I' currently testing whith a multi_array of
800x800x100 to hold double or pointers to double and I have memory
problems. When I declare the multi_array whith pointers to doubles I can
usually go up to 775x775x100 without problems but when I try the same
thing with a multi_array of doubles I get a bad alloc error. My real
needs for the moment are for a multi_array of 800x600x57 but I will need
bigger storage capacity in the near future, what are your sugesstions.
Is the multi_array a pointer itself?
How is memory management handled?
How can go beyond these limits?
