I am trying to merge small images into a large image by copying the small images' matrix to a single matrix While when i try copying, the result is not as I expected, the part of the large matrix is as the same as the image. The size of the small image is 13X39,hence i set it manually for testing
tryq=imread([folder '/' num2str(i+1) ' ' num2str(j+1) 'temp.jpg '])
figure(2)
imshow(tryq)
figure(3)
finalImage(1:13,1:39,:)=tryq;
imshow(finalImage);

I am not sure what result you are expecting that is different from what you got?
What did you initialize finalImage to be?

I am trying to make a mosaic image by combining the small image,
while on the figure2, the small image is yellow color image,
while when i copy to the the matrix in figure3,
it become mostly white What i wnat will be the image in the left will be exactly copy to the right one.
My finalImage is define as below
finalImage=zeros(row*blocksize(1),column*blocksize(2),3);
Where the row and column is the total small image i have,
and the blocksize is the size of the small image

That's because it's a double. Try this
finalImage=zeros(row*blocksize(1),column*blocksize(2),3, 'uint8');

Attached is a demo for copying a small image onto a larger one. In my demo, the small image is actually chosen from part of the large image, but it could just as well be a totally separate image.
