I am using Mathematica 5.1
Excuse me
calculation is :
m= Table[i^2+i*j*3.23.....,{i,10000},[j,10000} ];
Det[ m]
the program jams for lack of memory. Now neglecting the nature of the
calculation above suitable I wonder me because this happens
My computer has 1 GB of Ram, Processor AMD 3400+ , Win XP 32 Bit.
I have tried to plan the virtual memory to a superior value to 4 GBs
hoping to resolve the problem. Looking however at the virtual memory
during the calculation is seen that at the most 2,3 GBs are used only.
I have tried then to realize the calculation installing Win XP 64 Bit
with file system Ntfs + Mathematica 5.2 (64 Bit)4 GB RAM, but the
problem is not resolved
I think that increasing the RAM I could resolve but I don't understand
the nature of the problem. How is the memory managed? As it is
possible to esteem previously if my hardaware+software allows the
calculation that I want to perform?
Thanks for the help
