Hi,
I have a table of strings - see attached, and I want to be able to programatically identify and extract the identical part of the strings within that table.
For example, in the attached mat. the strings are:
'*EndoPart*' and '*EndoCort*'
Is there a way to identify the identical portion of the string ('Endo') in the entire column and extract it?
Thank you!

Actually the identical part at the start of the string is '*Endo', and this is easy to find:
>> X = logical(cumprod(all(diff(TableExample.group,1,1)==0,1)));
>> TableExample.group(1,X)
ans =
*Endo
There is also an identical part at the end of the string 'rt*', but I assume that you only want the identical part at the start.

Yes I am only interested in the identical part at the start.
Thank you, it worked like a charm on the table example.
I however tried on my data and I keep getting this error:
"Check for missing argument or incorrect argument data type in call
"to function 'diff'
I have attached my table. I'm not sure what I am doing wrong.
% The code I run is identical and the datatype is the same.
% Might you have any idea whats going wrong here?
X = logical(cumprod(all(diff(TableExample2.group,1,1)==0,1)));
Thanks again

@David Mabwa : I don't think I can open that table with the MATLAB versions I have available to me.
Perhaps someone else might be so kind as to investigate this further.
