Can I make in Matlab Codder a function variable that is both persistent (Static) and has specified type like int16?

    persistent variable;
    variable= coder.opaque('int');

Gives me coder error:

??? Class mismatch (coder.opaque ~= double).
The class to the left is the class of the left-hand side of the assignment.

Also I cannot define anything before declaring it persistent so swapping lines doesn't help :-)

You should be able to do something like:

 persistent var;
 if isempty(var)
   var = zeros('int16');
 end
 ... use var ...

in your code. Then, "var" will be int16 and persistent.
