Hi I have this cell array, and want to extract character before and after the "__"
tdata = {'XX__TG','GB_TH','BN__TH'}';
I want to use regexp and return me
out1 = {'XX'; 'GB'; 'BN'};
out2 = {'TG'; 'TH'; 'TH'};
Thanks

>> tdata = {'XX__TG';'GB_TH';'BN__TH'};
>> spl = regexp(tdata,'_+','split');
>> spl = vertcat(spl{:});
>> out1 = spl(:,1)
out1 =
'XX'
'GB'
'BN'
>> out2 = spl(:,2)
out2 =
'TG'
'TH'
'TH'
