MATLAB: When was ‘tokenize’ dropped from regexprep

regexpreptokenize

With R2016a I get this warning

>> regexprep( 'abc123def', '(\d{3})', '.$1.', 'tokenize' )
Warning: The 'tokenize' option for regexprep is now the default behavior. 
ans =
abc.123.def

Which was the first release in which 'tokenize' was the default? I don't find 'tokenize' in the current documentation. Will it be dropped altogether?

R14

You'll have to write a book about regexp after all these threads ;-)

EDIT: found it mentioned in the PDF release note "The MATLAB 7.0.4 Release Notes describe the changes introduced in the latest version of MATLAB for R14SP2" to be precise.

This should get you started:

>> str = '5*0.02 0.02 0.04 0.08 0.15 0.3 0.5 1 2 3 30*5 30*10 30*20 30*40 30*60';
>> fun = @(n,c)repmat(sprintf(' %s',c),1,str2double(n)); % or JOIN rather than SPRINTF.
>> str = regexprep(str,'\s*(\d+)\*(\S+)','${fun($1,$2)}')
str =
 0.02 0.02 0.02 0.02 0.02 0.02 0.04 0.08 0.15 0.3 0.5 1 2 3 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 40 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60 60

If you use join then you can get rid of the leading \s*.

MATLAB: Do I receive an error using the REGEXPREP function in MATLAB 6.5 (R13)

This enhancement has been incorporated in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This is a known change, and has been included in the Release Notes for MATLAB 6.5 (R13).

In MATLAB 6.5 (R13), if you want REGEXPREP to replace using tokens, you need to use the 'tokenize' option.

Change the second line of code to:

y=eval(['[''',regexprep(x,'\#(\d+);',''',char($1),''','tokenize'),''']'])
