Argh. Sorry, in my pre-coffee fog I didn't see that Puneet was
actually *answering* Cliff's question. Sorry, all. Next time I'll
wait till I'm fully awake...
Cliff, that error looks as if NiceSlice isn't parsing your line
properly. Do you have a "use PDL::NiceSlice;" near the top of your
script? (You have to invoke NiceSlice on a per-file basis, since it
uses the Perl source filter mechanism; this can be confusing if you're
moving commands from the perldl shell, because perldl jumps through a
lot of hoops to do it invisibly for you...)

I guess what I should have done was brought my "Also" to the top of
the print. I didn't realize that it doesn't supposed to do this.
Attached is the script.
Also I have
use PDL::NiceSlice ;
in the script, I still need to use ' ' around the values when
running the script in Windows (win32 ActiveState Perl 5.10). I am
debugging it in Eclipse with the EPIC plugin, and have also tried it
at the command line with the same results.
Without the single quotes which is what does work in perldl shell
$iob4 = $pic(0,$_:$picSize-1:6);
when I run it in Eclipse or Windows Command Prompt I get the
following error:
non piddle ref ' at C:/Perl/site/lib/PDL/Core.pm line 1645.

Subject: Re: [Perldl] Nice Slice Selection confusion
Puneet, by enclosing the niceslice terms in quotes, you are forcing
them to be evaluated as strings rather than as Perl variables.
Leave off the quotes.

Hi Folks,
I am struggling to understand the slice indexing syntax for $a-
>slice( a:b:c ). I did this in perldl shell:
pdl> $a=sequence (3,10);p $a
[
[ 0 1 2]
[ 3 4 5]
[ 6 7 8]
[ 9 10 11]
[12 13 14]
[15 16 17]
[18 19 20]
[21 22 23]
[24 25 26]

]
pdl> p $a(1,0:9:2)
[
[ 1]
[ 7]
[13]
[19]
[25]
]
and it worked like I expected it to.
I then put it in to my script
foreach (0..5) {
print $pic;
$iob4 = $pic('0','$_:$picSize-1:6');
print "iob4 is $iob4 of size ",nelem($iob4),"\n";
and i only get a single value - the first one:
[
[5.7863319e+008 5.5061404e+008]

iob4 is
[
[5.7863319e+008]
]
of size 1
Where I expected to get the first column with every 6th entry
starting from the first element in the column.
What am I doing wrong.
Also I have
use PDL::NiceSlice ;
in the script, I still need to use ' ' around the values when
running the script in Windows (win32 ActiveState Perl 5.10). I am
debugging it in Eclipse with the EPIC plugin, and have also tried
it at the command line with the same results.
The single quotes are screwing up here. They are being evaluated as
0, so, in effect, your niceslice expression is becoming $pic(0,0)
Consider
my $pdl = sequence (3,10);
print "pdl: " . $pdl(1,0:9:2) . "\n";
my $c = $pdl('0','0:9:2');
my $d = $pdl(0,0);
print "c is $c of size ", nelem($c), "\n";
print "d is $d of size ", nelem($d), "\n";
I get
pdl:
[
[ 1]
[ 7]
[13]
[19]
[25]
]
c is
[
[0]
]
of size 1
d is
[
[0]
]
of size 1
