Saving User Defined Class in MATLAB

Question

I have class in matlab using classdef as,

classdef scores
    %   SCORES Summary of this class goes here
    %   Class for stroring the individual scores array of each of the
    %   comparison of the models and the test files including the number of
    %   coefficients used and number of gaussian 

    properties
        detailed_scores;
        no_of_gauss=0;
    end

    methods
    end
end

Created objects and saved into an array as;

for i=1:99
    score = scores;
    score.detailed_scores = somescore(:,9);
    score.no_of_gauss = i;
    array = [array score];
end

Now, I would want to save it into a matfile as;

save('somematfile.mat','array');

Is it possible to load this array later on to retrieve the data back ?

Yes, load somematfile would just do that.

load somemathfile
for k = 1:length(array)
  obj = array(k);
  obj.detailed_scores
end

However, you have to be careful if you change the class definition, especially if you remove/rename or add new properties to the class. In that case you may need to implement saveobj and loadobj methods.
