print an array to .txt

Didn't find a good explanation.

Suppose we have an array R=[..,..,..] How to save this single array to a .txt file? Thank you.

It depends on the contents of the variable. If it e.g. a nested struct or cell array, you need another approach than for a simple string. How should the created file look like?

Array(n,1)

Just like a column of numbers, the question is still actual, please answer.

Vadim - try using fprintf. For example,

 % open your file for writing
 fid = fopen('myTextFile.txt','wt');

 % write the matrix
 myData = randi(255,10,3);
 if fid > 0
     fprintf(fid,'%d %d %d\n',myData');
     fclose(fid);
 end

The above is a very simple example that is based on the examples in the provided link so see that link for more details.
