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]
[27 28 29]
]
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]
[5.7863344e+008 5.5635026e+008]
[ 5.790996e+008 5.3051317e+008]
[5.7875504e+008 5.3033015e+008]
[5.7936432e+008 5.277951e+008]
[5.7675125e+008 5.6184104e+008]
[5.7871172e+008 5.5064908e+008]
[ 5.786631e+008 5.5618585e+008]
[5.7911588e+008 5.3037927e+008]
...
[5.7905481e+008 5.2330437e+008]
[5.7738847e+008 5.607879e+008]
[5.7844745e+008 5.5221171e+008]
[5.7900191e+008 5.5709251e+008]
[5.7942135e+008 5.2928743e+008]
[5.7908425e+008 5.286075e+008]
[5.7902203e+008 5.2338163e+008]
[ 5.774559e+008 5.6077705e+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.
Thanks,
