MB or KB ? I thought that each record is 3 doubles ?
3*4*8*1600 = 150 kB
3*4*8*1600*1600/2 = 117 MB for array like :
(x), // count=1
(x,x), // count=2
(x,x,x), // count=3
//...
(x,x,x,x,x.....) // count = 1600
117 MB is too big in fact... so maybe generate only support every 10-th
copunt above 300 ?
so count can be : 1,2,3...299,300, 310,320,330...
and every 20-th >600 600,620,640...
in that way array for count=3000 could be about hmm 50 MB i estimate ?
It can be downloaded as separate file from ftp://
