NAME¶
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 yet
I/O Utilities¶
ccs_writefraw¶
Write a pair of raw binary files using PDL::IO::FastRaw::writefraw().
ccs_writefraw($ccs,$fname) ccs_writefraw($ccs,$fname,\%opts)
Options %opts:
Header => $Header, ##-- default="$fname.hdr" ixFile => $ixFile, ##-- default="$fname.ix" ixHeader => $ixHeader, ##-- default="$ixFile.hdr" nzFile => $nzFile, ##-- default="$fname.nz" nzHeader => $nzHeader, ##-- default="$nzFile.hdr"
ccs_readfraw¶
Read a pair of raw binary files using PDL::IO::FastRaw::readfraw().
$ccs = ccs_readfraw($fname) $ccs = ccs_readfraw($fname,\%opts)
Options %opts:
Header => $Header, ##-- default="$fname.hdr" ixFile => $ixFile, ##-- default="$fname.ix" ixHeader => $ixHeader, ##-- default="$ixFile.hdr" nzFile => $nzFile, ##-- default="$fname.nz" nzHeader => $nzHeader, ##-- default="$nzFile.hdr" sorted => $bool, ##-- is data on disk already sorted? (default=1)
ccs_mapfraw¶
Read a pair of raw binary files using PDL::IO::FastRaw::readfraw().
$ccs = ccs_mapfraw($fname) $ccs = ccs_mapfraw($fname,\%opts)
Global options in %opts:
Header => $Header, ##-- default="$fname.hdr" ReadOnly => $bool, ##-- read-only mode? Dims => \@dims, ##-- logical dimensions (~ \@pdims) Datatype => $type, ##-- CCS::Nd datatype Creat => $bool, ##-- create file(s)? Trunc => $bool, ##-- truncate file(s)?
CCS::Nd options in %opts:
flags => $flags, ##-- CCS::Nd flags nnz => $nnz, ##-- CCS::Nd nnz pdims => \@pdims, ##-- CCS::Nd physical dimensions vdims => \@vdims, ##-- CCS::Nd virtual dimensions sorted => $bool, ##-- is data on disk sorted? (default=1)
Component options in %opts, for ${c} in qw(ix nz):
"${c}${opt}" => $cValue, ##-- override global option ${opt}
"${c}File" => $cFile, ##-- default="$fname.${c}"
"${c}Header" => $cHeader, ##-- default="$cFile.hdr"
