Plot images with iterative names as subplots

I have several images that I have read in as A1 to A43. For instance,

A1= imread('False_Color/20181007.png'); 
A2= imread('False_Color/20181015.png'); 
A3= imread('False_Color/20181023.png'); 

Then I am trying to use a loop to print all 43 images since the names are so similar. I think I am close, but I can't figure out how to remove the quotes so that I can plot imagesc(A3) instead of imagesc('A3') which of course does not work. Please let me know if there is another function I should be using instead of sprintf. Thank you!

This is what I am doing:

for i=1:length(dates_over)
    f1=figure(1)
    subplot(5,9,i)
    imagesc(sprintf('%s%d','A',i)) %I want to loop through so it does imagesc(A1) then imagesc(A2) then imagesc(A3) etc
    title(sprintf('%s',dates_over(i)),'fontsize',12)  %this works 
end

First you need to fix the way you read in the images. They should go into the elements of a cell array likse so,

A{1}= imread('False_Color/20181007.png'); 
A{2}= imread('False_Color/20181015.png'); 
A{3}= imread('False_Color/20181023.png');
...
A{43}=...

and then you would do,

for i=1:length(dates_over)
    f1=figure(1)
    subplot(5,9,i)
    imagesc(A{i}) %I want to loop through so it does imagesc(A1) then imagesc(A2) then imagesc(A3) etc
    title(sprintf('%s',dates_over(i)),'fontsize',12)  %this works 
end

Thank you! I knew there was a smarter way!
