NAME

PDL::SV - PDL subclass for keeping scalar data (like strings)

VERSION

version 0.006004

SYNOPSIS


            

              
              
use PDL::SV ();
my $p = PDL::SV->new( [ qw(foo bar) ] );

DESCRIPTION

This PDL::SV class stores array of scalar values. It can be used for vectors of strings.

While this class is a subclass of PDL, its internals are quite different from other normal PDL types. So basically what's not documented are not guaranteed to work.

METHODS / BASIC

These methods basically have similar behavior as PDL class's methods of same names.

slice


            

              
              
slice(...)

dice


            

              
              
dice(...)

glue


            

              
              
$c = $a->glue($dim, $b, ...);

Glue two or more PDLs together along an arbitrary dimension. For now it only supports 1D PDL::SV piddles, and $dim has to be 0.

uniq


            

              
              
uniq()

BAD values are not considered unique and are ignored.

uniqind()

Return the indices of all uniq elements of a piddle.

sever


            

              
              
sever()

set


            

              
              
set(@position, $value)

at


            

              
              
at(@position)

unpdl


            

              
              
unpdl()

list


            

              
              
list()

copy


            

              
              
copy()

inplace


            

              
              
inplace()

where


            

              
              
where($mask)

METHODS / BAD VALUE

These methods basically have similar behavior as PDL class's methods of same names.

isbad


            

              
              
isbad()

isgood


            

              
              
isgood()

ngood


            

              
              
ngood()

nbad


            

              
              
nbad()

setbadif


            

              
              
setbadif($mask)

setbadtoval


            

              
              
setbadtoval($val)

Cannot be run inplace.

METHODS / ADDITIONAL

These methods exist not in PDL but only in this class.

match_regexp


            

              
              
match_regexp($pattern)

Match against a plain regular expression. Returns a piddle of the same dimension.
