If you extract the _contents_ of each cell from that cell array, those contents will not include a single quote (unless one was present in the original text.) c{1} -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
From: Andy on 19 Jul 2010 11:24 Just because you did not get an immediate reply is no reason to repost your question several times. Please tell us more about what you're trying to do. Specifically, if you do not want textscan to return strings, why do you use '%s' as your format string? Perhaps you should start by reading the documentation for textscan.

See also regexp, strfind, strtok, ismember, eq, and http://www.mathworks.com/access/helpdesk/help/techdoc/learn_matlab/f2-644.html#f2-800 And next time, please do not post the same question 4 times. In the time you spent impatiently waiting for someone to answer, you could have searched the matlab help for keywords such as "string" and found appropriate operations.
