Hi,
I have an array of strings: L_Name. Each string has several "_" in it. I would like to have an array that take the first part in each string by '_'. I tried to use strfind, or reg, but just cannot get it.
How to do that? Thanks! JF

>> C = {'L_Name','Z_Y_X','Aaaa_BBBB','MMM'};
>> D = regexp(C,'[^_]+','once','match');
>> D{:}
ans = L
ans = Z
ans = Aaaa
ans = MMM

The nice thing is, it also works for an array of strings (the new string data type that MATLAB now has) in addition to the cell array Stephen showed:
C = ["L_Name","Z_Y_X","Aaaa_BBBB","MMM"]
D = regexp(C,'[^_]+','once','match');
D{:}
