Reading Multiple Images Using For Loop

I am trying to use a for loop to read 4 images (of the format 1.jpg,2.jpg etc...) and then calculate the value and location of the minimum pixel of each image. Below is the code I have so far:

RGB=cell(1,4);
for i=1:4
RGB{i}=imread(sprintf('%d.jpg',i)); %Converting the image in to a RGB matrix

gray{i}=rgb2gray(RGB{i}); %Converting the RGB image to grayscale
gray_double{i}=double(gray{i}); %Changing from uint8 format to double

Min_pixel{i}=min(gray_double{i}(:)); %Finding the minimum pixel value
[row, column] = find(gray_double == Min_pixel,1);%Finding location of first minimum

end;

The code works up until Line 8 where it struggles to obtain the minimum pixel value. Is there an easier way to do this?
