PDL::CCS::IO::FastRaw - PDL::IO::FastRaw wrappers for PDL::CCS::Nd
SYNOPSIS
use PDL;
use PDL::CCS::Nd;
use PDL::CCS::IO::FastRaw;
$ccs = PDL::CCS::Nd->newFromWhich($which,$nzvals);
ccs_writefraw($ccs,$fname); # write a pair of raw files
$ccs2 = ccs_readfraw($fname); # read a pair of raw files
$ccs3 = ccs_mapfraw($fname,{ReadOnly=>1}); # mmap a pair of files, don't read yetI/O Utilities
ccs_writefraw
