Creating a list of images in Matlab

I have a bunch of images of different resolution that I'd like to keep in a list.

Such that list(1) would be the first image, list(2) would be the second image, and so on.

I am using impyramid to create multiple resolution versio开发者_如何学Gons. Not sure how to do this.

The only real way to do this (because your images could have different dimensions) is to keep a cell array of them:

list{1} = im1;
list{2} = im2;
