MATLAB: Creating .mat file

1.) If the images are the same size you can put them in an array and save that. If different, use a cell array.

2.) You can use matfile() to create a writable .mat file, save data into it, and then load that.

    matobj = matfile('c:\data\mymat','Writable',true);
    matobj.image1 = randn(256,256);
    matobj.image2 = randn(256,256);
    loadimage1 = matobj.image1; 
    % or
    load('mymat.mat','image1');
