I want to extract the" name" of a filename without the extension- How do I use textscan to do this?

So what is the option to specify when to stop reading if a period (.) is encountered? name=textscan(filename,???)

This is not clear, the title and the content of your question are completely different

The question in the subject line ("extract the" name" of a filename without the extension") can be solved with fileparts():

[folder, baseFileNameNoExt, extension] = fileparts(fullFileName);

For the question in the body of the message, there is not enough information, but I'll take a guess at this:

% So what is the option to specify when to stop reading if a period (.) is encountered? name=textscan(filename,???)
fileName = 'abc.567.90xyz.txt'
dotLocations = find(fileName == '.')
if isempty(dotLocations)
	% No dots at all found so just take entire name.
	nameBeforeFirstDot = fileName
else
	% Take up to , but not including, the first dot.
	nameBeforeFirstDot = fileName(1:dotLocations(1)-1)
end
