Error trying to plot 2 images with different size using matlab

I have 2 images that I need to plot in one figure then display the points of interest found with SURF on both images: Image 1 : size [6113x5693x3] Image 2 : size [4896x3744x3] when trying to plot both of images in one figure with this code:

I = zeros([size(I1,1) size(I1,2)*2 size(I1,3)]);
I(:,1:size(I1,2),:)=I1;
I(:,size(I1,2)+1:size(I1,2)+size(I2,2),:)=I2;
figure, imshow(I); hold on;

and to display the points of interest of each one of them with :

plot([Pos1(:,2) Pos2(:,2)+size(I1,2)]',[Pos1(:,1) Pos2(:,1)]','-');
plot([Pos1(:,2) Pos2(:,2)+size(I1,2)]',[Pos1(:,1) Pos2(:,1)]','o');

I get this error and I dont know how to fixed :

Subscripted assignment dimension mismatch.

Any suggestion will be welcome!

Walk through this line by line. The error occurs on line 3. You are trying to assign I2 (with dimension 4896x3744x3) to a select part of I that has an incorrect first dimension (since the first dimension of I is the same as I1, not I2). 

size(I(:,size(I1,2)+1:size(I1,2)+size(I2,2),:)) = [ 6113  3744  3 ]

size(I2) = [4896 3744  3]
