Hi all,
I'm a PDL novice interested in processing instrument data which has
several codes for bad data. Since it seems that there can only be a
single bad data value, I can do this:
my $work = $original->copy;
for my $bv ( -9999, -8888, -7777 )
{
$work->inplace->setvaltobad($bv);
}
# process $work PDL, ignoring bad values
After processing I need to restore the values marked as BAD before
writing output. Using the above example, how can I copy from the
$original PDL the values corresponding to the BADs in the $work PDL? Of
course I could do it in a loop, but is there a PDL function like
merge($a, $b, mask)
Signature: (a(); b(); mask(); int [o]c())
Copies values from $b if $mask is true, otherwise copies from
$a.
Thanks.
Tod
