Hi, Suppose I have a 500MB-ram Computer and a 300MB ram-only (standard) numarray. Now I would like to "save" that onto harddrive (with a small header up front
f = open(filename, 'wb') f.write(MyHeader) A.tofile(f)
To read it back in, you need to know where your header ends, by either parsing it or using one of the same size every time, then you can use fromfile() to create an array form it.
The main reason for my question was just to find out if NUMARRAY supports it, and how ? Also I have many "bookkeeping" functions already implemented for the memmap'd case. (That is, I have a class with member methods operting on a member memmapped array) So if what I descibed is possible I could save myself form duplicating lot's of code.
Essentially I was hoping for the most ellegant solution ;-)
