How do you plot values from a cell array?

%Bulk modui 
Km = Em/(3*(1-2*vm)); 
Kf = Ef/(3*(1-2*vf));
%Moduli referred to lamina axes 
E1 = Em*Vm+ (Ef*Vf);
%passions ratio

v12 = (vm*Vm)+ (vf*Vf) + (top/bottom);
%Shear modulus

%bulk modulus

   % z = cell2mat(strain_xx{k1});
  % hold on ;
   %plot (Angle, strain_xx{k1}); hold on;
    %grid on;
   %mesh(Angle, strain_xx{k1})   
end

At the end of this piece of code I want to plot strain_xx but I can't because it is a cell array can anyone help?

plot(cell2mat(strain_xx))
