24 Sep 2009 CELL2STR CELL2STR converts a cell array of strings into a character array. Author: Daniel Claxton

Although Jos and us are right, I think this function deserves to stay here, because its name is more intuitive that the built-in 'char', which is not expected to do the conversion. The high number of downloads of this function seems to confirm my opinion. Best regards, MC

I would tend to agree with Mr. Shvorob and Mr D'Errico, this is not what I understand orthogonal least-squares. Also, although the code is not as poor as previously seen entries, the general structure is confusing and unnecessarily bloated. In particular, I find the choice to include a demo capability into the function itself, rather than including it as a seperate file, questionable to say the least.

None the less, I'm sure that with a good cleanup, this code will find its uses in some scenarios, if not for the functionality it offers then for its thorough discussion of the theory (although it should probably be moved out of the file to a seperate document).

Thank you Jos! I have updated the submission using your suggestion!

Better to use the oneliner:
    
% data
V = [1 2 3 4.5 6 pi] ;
prestr = 'Text before '
poststr = ' .. and after '
formstr = '%.2f' ;
    
% engine
C = cellstr(num2str(V(:),[prestr formstr poststr]))
