Hello
I want to save a too large matrix (4000000x4000000)
Maximum possible array: 16664 MB (1.747e+10 bytes) *
Memory available for all arrays: 16664 MB (1.747e+10 bytes) *
Memory used by MATLAB: 1077 MB (1.129e+09 bytes)
Physical Memory (RAM): 8097 MB (8.490e+09 bytes)
  • Limited by System Memory (physical + swap file) available.
I have increased the virtual memory to 12000 MB
Please, i want to avoid the loops in order to get faster to the solution (optimization)
Thank you for your help

A double-precision numeric array of size 4,000,000 x 4,000,000 would require over 122 MILLION megabytes of storage. (Over 116 terabytes.) That's not feasible.
You will need to find some other way.
