% Customizable natural-order sort of a cell array of strings.
%
% © 2012 Stephen Cobeldick
%
% ### Function ###
%
% Sort the strings in a cell array of strings by character order (ASCII)
% and the value of any numeric tokens.
%
% By default sorts case-insensitive ascending, with integer numeric tokens.
% Optional inputs may be used control the format of the numeric tokens
% within the strings (see ‘Tokens’), case sensitivity and sort direction.
%
% Syntax:
% SortedCellStr = sortnat(CellStr)
% [SortedCellStr,SortIndex] = sortnat(CellStr,…);
% […] = sortnat(CellStr,RegExp)
% […] = sortnat(CellStr,RegExp,Case)
% […] = sortnat(CellStr,RegExp,Case,Descend)
% […] = sortnat(CellStr,RegExp,Case,Descend,Format)
%
% See also SORT SORTROWS UNIQUE CELLSTR REGEXP SSCANF
%
% ### RegExp Tokens ###
%
% # A numeric token consists of some combination of digits, may optionally
% include a +/- sign, decimal point, exponent, etc. The numeric tokens
% must be able to be parsed by “sscanf” (default format ‘%f’), and may
% be defined by the optional “regexp” regular expression input, eg:
%
% Regular Expression Example: | Matches Numeric Token:
% ----------------------------|---------------------------------
% ‘\d+’ | integer (default).
% ----------------------------|---------------------------------
% ‘(-|+)?\d+’ | integer with optional +/- sign.
% ----------------------------|---------------------------------
% ‘\d+(.\d+)?’ | integer or decimal.
% ----------------------------|---------------------------------
% \d+|inf | integer or infinite value.
% ----------------------------|---------------------------------
% ‘(-|+)\d+.\d+’ | decimal with +/- sign.
% ----------------------------|---------------------------------
% ‘\d+e\d+’ | exponential.
% ----------------------------|---------------------------------
% '[1-9]\d
|(?<=0?)0(?!\d)’ | integer excluding leading zeros.
%
% # A character is any other single character: all other characters not
% matching the “regexp” pattern, including space & non-printing characters.
%
% ### Examples (comparison with “sort”) ###
%
% # Integer numeric tokens:
%
% A = {‘File2.txt’,‘File10.txt’,‘File1.txt’};
% sort(A)
% ans = {‘File1.txt’,‘File10.txt’,‘File2.txt’}
% sortnat(A)
% ans = {‘File1.txt’,‘File2.txt’,‘File10.txt’}
%
% # Integer or decimal numeric tokens, possibly with +/- signs:
%
% B = {‘File102.txt’,‘File11.5.txt’,‘File-1.4.txt’,‘File+0.3.txt’};
% sort(B)
% ans = {‘File+0.3.txt’,‘File-1.4.txt’,‘File102.txt’,‘File11.5.txt’}
% sortnat(B,’(-|+)?\d+(.\d+)?’)
% ans = {‘File-1.4.txt’,‘File+0.3.txt’,‘File11.5.txt’,‘File102.txt’}
%
% # Integer or decimal numeric tokens, possibly with an exponent:
%
% C = {‘A_0.56e+07’,‘A_4.3E2’,‘A_10000’,‘A_9.8’}
% sort©
% ans = {A_‘0.56e+07’,‘A_10000’,‘A_4.3E2’,‘A_9.8’}
% sortnat(C,’\d+(.\d+)?(e(+|-)?\d+)?’)
% ans = {‘A_9.8’,‘A_4.3E2’,‘A_10000’,‘A_0.56e+07’}
%
% # ASCII order (including non-printing characters):
% sortnat(CellStr,’[]’,true);
%
% ### Inputs and Outputs ###
%
% Outputs:
% Out = CellOfStrings, InC sorted into natural-order, same size as InC.
% ind = Numeric array, such that OutCoS = InCoS(ind), same size as InC.
% For debugging: each row is one string, linear-indexed from InC:
% ChA = Character array, all separate non-numeric characters.
% NuA = Numeric array, “sscanf” converted numeric values.
%
% Inputs:
% InC = CellOfStrings, whose string elements are to be sorted.
% tok = String, “regexp” numeric token extraction expression, ‘\d+’
.
% cse = Logical scalar, true/false* -> case sensitive/insensitive.
% dsc = Logical scalar, true/false* -> descending/ascending sort.
% fmt = String, “sscanf” numeric token conversion format, ‘%f’.
%
% An empty input [] uses the default input option value (indicated ).
%
% Outputs = [Out,ind,chr,num]

function [cs,index] = sort_nat(c,mode)
%sort_nat: Natural order sort of cell array of strings.
% usage: [S,INDEX] = sort_nat©
%
% where,
% C is a cell array (vector) of strings to be sorted.
% S is C, sorted in natural order.
% INDEX is the sort order such that S = C(INDEX);
%
% Natural order sorting sorts strings containing digits in a way such that
% the numerical value of the digits is taken into account. It is
% especially useful for sorting file names containing index numbers with
% different numbers of digits. Often, people will use leading zeros to get
% the right sort order, but with this function you don’t have to do that.
% For example, if C = {‘file1.txt’,‘file2.txt’,‘file10.txt’}, a normal sort
% will give you
%
% {‘file1.txt’ ‘file10.txt’ ‘file2.txt’}
%
% whereas, sort_nat will give you
%
% {‘file1.txt’ ‘file2.txt’ ‘file10.txt’}
