Hi,

I'm having some difficulty clearing a persistent variable from inside a static method. My code is something like this:

classdef MyClass
  properties
      % code...
  end
  methods (Static)
      function obj = firstStatic(a,b)
      % trying to get this function to use a and b to overwrite the persistent obj in secondStatic
          clear MyClass
          obj = secondStatic(a,b)
      end
      function obj = secondStatic(a,b)
      % this should collect the persistent obj that firstStatic populated
         persistent perVar
         if isempty(perVar)
            perVar = % work out perVar from a and b
         end
         obj = perVar
      end
end
