Hello -
I have a perl script that writes a large amount of data to binary
files using the PDL::IO::FastRaw "writefraw" command and it is really
slow when writing out the data. Significantly slower (~4 times) than
when I write the same amount of data using a C program. I would
prefer to use a perl script rather than C but have not been able to
speed up the write time.
This is a slice of my code
$outfile = "junk";
$outdata = $data_nwp->clump(2)->($xy_index_nwp ->clump(-1));
open OUTFILE, ">$outfile" or die "Can not open file $outfile for
write :$!\n";
binmode OUTFILE;
writefraw($outdata,*OUTFILE);
close OUTFILE;
$outdata is a PDL of dimensions 334695 169
Is there another module which would be better to use? Has anyone
else had this problem?
Thanks for your time!
Amy
