set method for class

Hy I got this class, that i use to store some data. i made the festi property dependant but now i realize that i have to call this function really often ( 100 000) during the program and since there are several awitches and severeal other defenitions within it ( i didt copy the hole code) it makes it to slow. actually i use the values a lot but i dont often change the values.

so it would be nice to save the container that would make it fatser because then i could reach the values throught the container without going throught all the swiches and ifs.

i copied my new solution unter the first try.

i would be thankfull for any help thanx

classdef material
      properties
          name     %string
          strengthClass    %string
      end%properties
      properties (Dependent)
          festi         % dictionary or containers.Map
      end%properties
      methods
          function m = material(name,strengthClass)
              m.name=name;
              m.strengthClass = strengthClass;
          end

            function obj = get.festi(obj)
                F_NadelundLaub=[14,16... % some matriy with date
                keys_NHuLH={'fmk','ft0k','ft90k','fc0k'};
                F_BSH=[24,....  other matrix with data
                ...   
                    if strcmp(obj.name,'Nadelholz')
                        switch obj.strengthClass
                            case 'C14'
                                values =F_NadelundLaub(:,1);
                            case 'C16'...
                        end
                    end  
                end %eleseif
                val = containers.Map(keys,values);
            end
        end  %methods
    end  %CLASS

% the other way

classdef material
    properties
        name     %string
        strengthClass    %string
        festi         % dictionary
    end%properties
    methods
        function m = material(name,strengthClass)
            m.name=name;
            m.strengthClass = strengthClass;
            m.festi = Festigkeitswerte2(m.name,m.strengthClass); % this one works
        end

      end  %methods
  end  %CLASS

% to change it outside the class i could use:

instanceofMaterial.festi = Festigkeitswerte2('Nadelholz','C14')

% this one works too but im looking for a mor eleagant way

It looks like the festi property only depends on the strengthClass property. You could create a set method for strengthClass which updates festi.
