Is there a possibility to join the strings out of cells in cells?

Dear Matlab-community,

i have many cells in cells, here is a simple example: Testfile = {'String1', 'String2';{'String3';'String4'}, {'String5';'String6'}};

I would like to have somthing like this: first cell: String1.String3,String1.String4 second cell: String2.String5,String2.String6

Is there a fuction, which helps to extract the cell information easier, then looping over all cells?

What exactly is "first cell: String1.String3" Please post valid Matlab code to define the wanted output uniquely.

I think that's what you want. If not as per Jan's comment, use valid matlab syntax to define the desired output

cellfun(@(s, c) compose('%s.%s', s, string(c)), Testfile(1, :), Testfile(2, :), 'UniformOutput', false)

Requires R2016b or later for compose and string.

Also thank you for your comment Guillaume!

There is no standard function to solve this special problem. Therefore a loop is the best and easiest idea.

I do not understand, what you want as output, but perhaps:

T  = {'String1',             'String2'; ...
     {'String3';'String4'}, {'String5';'String6'}};
nT = size(T, 2);
R  = cell(1, nT);
for iT = 1:nT
   R{iT} = sprintf('%s.%s,%s.%s', T{1, iT}, T{2, iT}{1}, T{1, iT}, T{2, iT}{2});
end

Result:

R = {'String1.String3,String1.String4', ... 
     'String2.String5,String2.String6'}

Maybe you want another result, but the method should be equivalent.
