I have two csv files of different sizes. The output file needs to have file1 contents on top of file2 contents where file2 col1 is >= to file1 col1, and file2 col1(same value) is < file1 col1 (next value). So basically, some file2 rows will be matched to the same file1 row because it is the closet... (7 Replies)

pdl::char
Char(3) User Contributed Perl Documentation Char(3)NAME
PDL::Char -- PDL subclass which allows reading and writing of fixed-length character strings as byte PDLs
SYNOPSIS
use PDL;
use PDL::Char;
my $pchar = PDL::Char->new( [['abc', 'def', 'ghi'],['jkl', 'mno', 'pqr']] );
$pchar->setstr(1,0,'foo');
print $pchar; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'foo' 'ghi']
# ['jkl' 'mno' 'pqr']
# ]
print $pchar->atstr(2,0);
# Prints:
# ghi
DESCRIPTION
This subclass of PDL allows one to manipulate PDLs of 'byte' type as if they were made of fixed length strings, not just numbers.
This type of behavior is useful when you want to work with charactar grids. The indexing is done on a string level and not a character
level for the 'setstr' and 'atstr' commands.
This module is in particular useful for writing NetCDF files that include character data using the PDL::NetCDF module.
FUNCTIONS
new
Function to create a byte PDL from a string, list of strings, list of list of strings, etc.
# create a new PDL::Char from a perl array of strings
$strpdl = PDL::Char->new( ['abc', 'def', 'ghij'] );
# Convert a PDL of type 'byte' to a PDL::Char
$strpdl1 = PDL::Char->new (sequence (byte, 4, 5)+99);
$pdlchar3d = PDL::Char->new([['abc','def','ghi'],['jkl', 'mno', 'pqr']]);
string
Function to print a character PDL (created by 'char') in a pretty format.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['jkl' 'mno' 'pqr']
# ]
# 'string' is overloaded to the "" operator, so:
# print $char;
# should have the same effect.
setstr
Function to set one string value in a character PDL. The input position is the position of the string, not a character in the string. The
first dimension is assumed to be the length of the string.
The input string will be null-padded if the string is shorter than the first dimension of the PDL. It will be truncated if it is longer.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
$char->setstr(0,1, 'foobar');
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['foo' 'mno' 'pqr']
# ]
$char->setstr(2,1, 'f');
print $char; # 'string' bound to "", perl stringify function
# Prints:
# [
# ['abc' 'def' 'ghi']
# ['foo' 'mno' 'f'] -> note that this 'f' is stored "f "
# ]
atstr
Function to fetch one string value from a PDL::Char type PDL, given a position within the PDL. The input position of the string, not a
character in the string. The length of the input string is the implied first dimension.
$char = PDL::Char->new( [['abc', 'def', 'ghi'], ['jkl', 'mno', 'pqr']] );
print $char->atstr(0,1);
# Prints:
# jkl
