    Скрипт Open Live Script

    Создайте блокированное изображение. 

    bim = blockedImage('tumor_091R.tif');

    Создайте блокированный datastore изображений из блокированного изображения.

    bimds = blockedImageDatastore(bim);

    Разделите блокированный datastore изображений в два раздела и создайте новый blockedImageDatastore объект данных в первом разделе.

    bimdsp1 = partition(bimds, 2, 1);

    Считайте данные из первого раздела.

    disp('Partition 1');
    Partition 1

    while hasdata(bimdsp1)
      [data, info] = read(bimdsp1);
      disp(info);
