You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fiordos.m
    path of file: ./repos/YALMIP/extras/@optimizer
    
    the code of the file until where you have to start completion: function solver = fiordos(self)

% The first dimin equalities are used to fix some parameters
aux = self.model.F_struc(1:self.dimin,:);


    
function solver = fiordos(self)

% The first dimin equalities are used to fix some parameters
aux = self.model.F_struc(1:self.dimin,:);

% remove these 
self.model.F_struc(1:self.dimin(1),:) = [];
self.model.K.f = self.model.K.f - self.dimin(1);

% Extract all bounds and move from Ab to ub/lb
temp =  presolve_bounds_from_modelbounds(self.model,1);   
self.model = temp;
% Any bound constraints?
n = length(temp.lb);
bounded_ub = find(~isinf(temp.ub));
bounded_lb = find(~isinf(temp.lb));
if length(bounded_lb) == n && length(bounded_ub) == n
    % All have finite bounds.
    X = EssBox(n, 'l',temp.lb, 'u',temp.ub);
    X = SimpleSet(X);   
elseif  ~isempty(bounded_ub) || ~isempty(bounded_lb)
    % Only some bounds. Keep them as general constraints
    X = [];
    for i = 1:n
        if isinf(temp.lb(i)) && isinf(temp.ub(i))
            X{end
