This statement should do it xmlOutString = strjoin( xmlData, '\n' );

Hi Yash I have an understanding that you want to concatenate array. If a and b are cell arrays, then you concatenate them in the same way you concatenate other arrays: using []: >> a={1,'f'} a = 1×2 cell array {[1]} {'f'} >> b={'q',5} b = 1×2 cell array {'q'} {[5]} >> [a,b] ans = 1×4 cell array {[1]} {'f'} {'q'} {[5]} To append a single element, you can do a{end+1}=1 or a(end+1)={1}. Hope this helps Regards

The square brackets [] are a concatenation operator. To keep the individual strings as strings, use a cell array: parameters = {'K13','K24','K_52','K63','K74','K80','K101','K114','K162','MI','Ce','Ge','Pe'}; Note the curly brackets {} denoting a cell array. See the documentation section on MATLAB Operators and Special Characters

You can concatenate strings using strcat. If you plan on concatenating numbers as strings, you must first use num2str to convert the numbers to strings.

Also, strings can't be stored in a vector or matrix, so f must be defined as a cell array, and must be indexed using { and } (instead of normal round brackets).

f = cell(N, 1);
for i=1:N
   f{i} = strcat('f', num2str(i));
end

That would work as you expected if Cruise_ID were a char vector. In that case, the concatenation would make a longer char vector, one where each element is a single character. Cruise_ID = 'W2016' Cruise_N = 1; a = [Cruise_ID, ' [No. ', num2str(Cruise_N,'%.0f'), ']'] But it's not. It's a string array. Cruise_IDs = string(Cruise_ID) a = [Cruise_IDs, ' [No. ', num2str(Cruise_N,'%.0f'), ']'] In that case, MATLAB will convert the char vectors in your command into strings and then concatenate the strings together. What you receive would be a string array where each element is one of the sub-strings that you concatenated together. There are a few ways to always make a single piece of text. You could make at least one piece of the "fixed text" into a string and use the + operator. This, like concatenation, would convert the char vectors into strings and concatenate them together. It won't do what you expect if all the things you're "adding" together are char vectors, though. In this first example the "fixed text" segment " [No. " is a string so Cruise_ID, the output of num2str, and the ']' are all converted to strings before + adds them together. a = Cruise_ID + " [No. " + num2str(Cruise_N,'%.0f') + ']' You could use strcat. Note a subtle difference between this and the others: there's no space after the No. piece, and this is expected behavior. strcat trims trailing whitespace in its inputs before concatenting them together. a_char = strcat(Cruise_ID, ' [No. ', num2str(Cruise_N,'%.0f'), ']') a_string = strcat(Cruise_IDs, ' [No. ', num2str(Cruise_N,'%.0f'), ']') You could use sprintf. Note that the type of the output (char or string) depends on the type of the format specifier. a_charin_charout = sprintf('%s [No. %.0f]', Cruise_ID, Cruise_N) a_stringin_charout = sprintf('%s [No. %.0f]', Cruise_IDs, Cruise_N) a_charin_stringout = sprintf("%s [No. %.0f]", Cruise_ID, Cruise_N) a_stringin_stringout = sprintf("%s [No. %.0f]", Cruise_IDs, Cruise_N)
