The file you have appears to be a GeoTIFF file, which you can read with readgeoraster or the older geotiffread
You can write out the modified data using geotiffwrite
geotiffinfo might also be of interest.

The file appears to contain a __MACOSX subdirectory.
pwd
ls -la
!zipinfo -1 Test5.zip
D=unzip('Test5.zip')
ls -la

If understood your question correctly, this is how to get it solved:
D=unzip('Test5.zip');
%%
D1 = imread(D{1,1});
DS = load(D{1,3}).image_median;
subplot(211);imagesc(D1); title('doy2019190052709_aid0001.tif')
subplot(212); imagesc(DS); title('mymatrix.mat')
[X, Y] = find(DS(:,:,1)>0.9);
D1(X,Y,:)=DS(X,Y,:);
%%
figure
imagesc(D1); title('Updated TIFF file')
saveas(gcf, 'UPDATED.tiff') % Save the updated image data
