Could you try:

The match is greedy, meaning once you put a %s format, it 'eats up'
everything. You better split first into fields:
content = strsplit( loc, ',')
wil return a cell array of strings; convert them with str2num afterwards.
Now if you want direct conversion, you can use:
content = cellfun(@(x) str2num(x), strsplit(loc, ','), 'UniformOutput',
false);
to get an all-numeric result, except for the town name, which will result in
an empty numeric value.
