MATLAB: How to create an array and combine and put two images into it

arrayMATLAB

Hi.
So far, I have the following code:
A = imread('Yuan.jpg');
ACrop = A(300:1300, 300:1051);
imshow(ACrop)
B = imread('Jacky.jpg');
BCrop = B(1:225, 88:283);
imshow(BCrop)
I have two images cropped. I want to combine ACrop and BCrop together with ACrop on the left and BCrop on the left. How do I create an array so that I may combine two images into one in the array?
Thanks.

Maybe you need to resize or add white pixels so that the images have the same dimension.
A = imread('Yuan.jpg');
ACrop = A(300:1300, 300:1051);
imshow(ACrop)
B = imread('Jacky.jpg');
BCrop = B(1:225, 88:283);
imshow(BCrop)
[qq,ww,ee] = size(Acrop); 
matrix = 255*uint8(ones(qq,ww,ee)); %Image with pixels in 255 (White)
[rr,tt,yy] = size(Bcrop);
matrix(1:rr,1:tt,:) = Bcrop(:,:,:); %add Bcrop to the white matrix
umi = [ACrop, matrix]; %concatenate



imshow(umi)
%or

umi = [ACrop;matrix]; %concatenate
imshow(umi)
with resize: 
A = imread('Yuan.jpg');
ACrop = A(300:1300, 300:1051);
imshow(ACrop)
B = imread('Jacky.jpg');
BCrop = B(1:225, 88:283);
imshow(BCrop)
[qq,ww,ee] = size(Acrop); 
Bcrop = imresize(Bcrop,[qq ww]);
umi = [ACrop, Bcrop]; %concatenate
imshow(umi)
%or
umi = [ACrop;Bcrop]; %concatenate
imshow(umi)
