Regular expressions are very good for this:
km = {'ibadal202@gmail.com'
'qzaman@msn.com'
'dfoorno020@msn.com'
'myey@hotmail.com'
'qkemal@myspace.com'
'zvarfi1013@gmail.com'
'vlul010@mynet.com'
'uwardo@msn.com'
'izaman@hotmail.com'
'htimiro@myspace.com'
'mfoorno@hotmail.com'
'uelo@hotmail.com'};
numasstring = regexp(km, '\d+(?=@)', 'match', 'once') %find sequence of digits immediately followed by @.
numbers = cellfun(@str2double, numasstring)
