How declare a variable only once in a matlab function block and then use the previous value the nex time the function is used?

You could also use a persistent variable inside your MATLAB function block:

 

function y = fcn(sEMG5,sEMG6)
%#codegen

persistent servo2;

% set original servo positions to zero the
% first time this function is invoked
if isempty(servo2)
  servo2=0;
end

% Use servo2 here
...
