If you have deep learning toolbox, this can be easily acheieved with the augmented Image Data Store.

a = imageDatastore(foldername,'IncludeSubfolders',true);
size = [m n 3]
a = augmentedImageDatastore(size,a);

If you do not have deep learning toolbox you can use the transform function on image datastore to achieve the same results.

a = imageDatastore(foldername,'IncludeSubfolders',true);
m = 224;
n = 224;
targetSize = [m,n];
imdsReSz = transform(a,@(x) imresize(x,targetSize));

An example is available in the Matlab documentation.
