Hi all,
Do you recommend a way to work with bit matrices in Julia. By "big" I mean
a 65600 x 65600 symmetric matrix (the upper triangular matrix is equal to
the lower triangular one).
I am studying the distances between sites at different resolution maps. For
low resolution we have few sites, and for big resolution we have more sites
(S).
For few sites (small matrices) I was doing something like this:
S = 100;#number of sites
M = zeros(S,S);
for i in 1:(S-1)
for j in (i+1):S
M[i,j] = dist(i,j);#where dist(i,j) is the distance between sites i
and j
end
end
However, for big matrices I get the following message:
S=65600;
M = zeros(S,S);
ERROR: OutOfMemoryError()
in call at essentials.jl:201
in zeros at array.jl:233
I am using Julia Version 0.4.0-dev+5920 in Ubuntu 14.04.
Thanks for any tip!
Best,
Charles
