how do i join cell array strings for plotting

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.

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"
