FYI, the matrix you tried to allocate would hold
(3195*1290*495*35*35*35*15) * 3 = 3.936248e+15 values. Each value
would occupy 8 bytes of memory (for the double data type). In other
words, in order to keep this data matrix in memory you would require a
computer with at least 3.148998e+16 bytes of RAM, i.e. 29327331 GiB =
28640 TiB = 28 PiB. Storing such a large matrix even on file is not
In other words, you need to figure out how to approach your original
problem in a different way.
