Hi,

How could I extract the 2 far right characters from cell string?

tt= {'United Kingdom TR';'United Kingdom SR';'United Kingdom WR';'Worldwide TC'};

Below is very inefficient.

splitStr = regexp( tt, ' ','split');
for runi= 1: length( tt)
    ttxt = splitStr{runi};
    peril(runi) = string( ttxt(end));
end 

peril =

1×4 string array

"TR" "SR" "WR" "TC"

One approach that generates a cell array:

tt= {'United Kingdom TR';'United Kingdom SR';'United Kingdom WR';'Worldwide TC'};
c = cellfun(@(s)s(end-1:end), tt, 'UniformOutput', false)
c = 4×1 cell array
    {'TR'}
    {'SR'}
    {'WR'}
    {'TC'}

If you prefer, you can convert this result to a string array like this

string(c)
ans = 4×1 string array
    "TR"
    "SR"
    "WR"
    "TC"
