hi,
i have a 2 by 3 cell array. the rows looks like:
{["abc\_111"]} {["def\_111"]} {["ghi\_111"]}
{["abc\_123"]} {["abc\_456"]} {["abc\_789"]}
what i think i want to do is join all the elements in each row into a column so that i can use them in making a plot with set(gca, 'xticklabels',joined_string). i think the new joined_sting should look like this
{["abc\_111\_def\_111\_ghi\_111"]}
{["abc\_123\_abc\_456\_abc\_789"]}
i'm both not sure if this is the right way to do this or how to do this. i've tried join and i keep gettign error messages

The input format is strange: Strings inside a cell array? Either use a string array, or a "cell string", which is the historical term for a cell or char vectors. A cell of strings combines the drawbacks of both versions.

Ran in:
Dicide to use a better input format. Either a cell string:
C = {'abc\_111', 'def\_111', 'ghi\_111'; ...
'abc\_123', 'abc\_456', 'abc\_789'};
Or a string array:
S = ["abc\_111", "def\_111", "ghi\_111"; ...
"abc\_123", "abc\_456", "abc\_789"];
Then:
result = join(C, '\_', 2)
result = 2×1 cell array
{'abc\_111\_def\_111\_ghi\_111'} {'abc\_123\_abc\_456\_abc\_789'}
% or
result = join(S, '\_', 2)
result = 2×1 string array
"abc\_111\_def\_111\_ghi\_111" "abc\_123\_abc\_456\_abc\_789"
