save image or read image from file . mat

I felt so stupid to ask this question. But I need you to help because I do not know how resolved. I have one file "Input.mat" and I've read it. However, I do not know how to read, save individual images to user individually

load('Input.mat')
load('Target.mat')
for i=1: 195
    data=Input(:,:,i);
    imshow(data);
    pause(0.2);
end

Exactly what does "save individual images to user" mean? I am the user. How do you save images to me ???
