How to write cell array contents into m-file as shown below?

I have a cell Array vector as attached (length may vary). It contains variable names.

 mycell =
  5×1 cell array
    {'x'   }
    {'y'   }
    {'var1'}
    {'var2'}
    {'var3'}

How to print it in m-file as follows?

 out = [x;y;var1;var2;var3];

You could do it with eval but you shouldn't. (I have taken the liberty of adapting some of Stephen Cobeldick's thoughts on this topic) Introspective programing (eval and other functions like it) is slow, and the MATLAB documentation warns specifically against it. Using eval is slow, makes debugging difficult, and removes all code helper tools (code checking, syntax hints, code completion, variable highlighting, etc.). A longer discussion can be found here. If you are not an expert and you think you need eval, there are probably better solutions to your problem. Also, if you are not an expert, you might find interesting and helpful hints on this page (and if you are an expert, you can still learn from it).

Printing the strings of a cell array to an open file (with id fid) is easy, just use a combination of sprintf and fprintf, something like this:

str = sprintf(';%s',mycell{:});
fprintf(fid,'out = [%s];\n',str(2:end));

Note that meta-programming (automatically writing code and running it) is quite inefficient.

It's very helpful! Danke!
