MATLAB: Hi, how to adding value to array in existing array

adding arrayarray

I have aray containing headers and values from some feature extractions. I also have 275 images. When I run my code, I want the value from the overall extraction of my image to be stored in the same array without deleting the extraction value of the previous image feature. below I created a code that only stores feature extraction values from one image, when I run the code for the next image, the previous value disappears. Please help me to complete my code. Thanks
    header = {'area','perimeter','roundness','solidity','slimness','rectangu','NF','RPD'};
    classinfo = {Area Perimeter Round Slimness Rect soli NF RPD RPLW};
    Fitur = [header; classinfo];

Solution is to save the array in .mat file, therefore, for next time to run the script, it will load the mat file, and add new value to the variable/table in the .mat file.
%save in array matlab
try
load Fitur.mat
catch me
end
if exist('Fitur','var')~=0
height = size(Fitur,1);
ID =  height+1;
else
Fitur = [];
ID = 1;
end
classinfo = [ID area  perimeter  roundness solidity  slimness rectangu  NF  RPD...
                    RPLW M1  M2  M3 M4 M5 M6 M7  mu  deviasi  energi  entropi smoothness...
                    contrast homogenitas energi korelation];
Fitur = [Fitur; classinfo]; 
Fiturtable=array2table(Fitur);
header = {'ID' 'area','perimeter','roundness','solidity','slimness','rectangu','NF','RPD'...
              'RPLW','M1','M2','M3','M4','M5','M6','M7','mu','deviasi','energi','entropi','smoothness'...
              'contrast','homogenitas','energi2','korelation'};
Fiturtable.Properties.VariableNames = header;
save('Fitur.mat','Fitur','Fiturtable')
