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');

Single image how? Tiled, like with the montage() function? Or stacked into a volumetric 3D image like with cat(3, .....)?

Yes, you can create an image volume. Create a 3-D array and place the images in that array.
X = zeros(256,256,15);
X(:,:,1) = image1;
X(:,:,2) = image2;
and so on

Hi Wayne, is there a way to do it in a loop?? I have around 400 hundred matrices in my workspace and I want to store them in a 3d array. Thank you.
