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_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"

        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"
