Figure with 17x17 subplot

I need to make a big figure that contains 17x17 subplots. My question is how do I make this such that the plots although obviously small, are readable. Particularly in trying it, and plotting only the first row I get:

Which has two problems: 1) Titles cross with axis numbers. 2) There's plenty of space in the sides and top that is not used. Then, how could I fix this such that a 17x17 plots are a readable?

My code with only the first row and first 3 titles:

subplot(17,17,1)
plot(x1,y1)
title("Plot 1")
subplot(17,17,2)
plot(x1,y1)
title("Plot 2")
subplot(17,17,3)
plot(x1,y1)
title("Plot 3")
subplot(17,17,4)
plot(x1,y1)
subplot(17,17,5)
plot(x1,y1)
subplot(17,17,6)
plot(x1,y1)
subplot(17,17,7)
plot(x1,y1)
subplot(17,17,8)
plot(x1,y1)
subplot(17,17,9)
plot(x1,y1)
subplot(17,17,10)
plot(x1,y1)
subplot(17,17,11)
plot(x1,y1)
subplot(17,17,12)
plot(x1,y1)
subplot(17,17,13)
plot(x1,y1)
subplot(17,17,14)
plot(x1,y1)
subplot(17,17,15)
plot(x1,y1)
subplot(17,17,16)
plot(x1,y1)
subplot(17,17,17)
plot(x1,y1)

Another option is use function tiledlayout

tiledlayout(17,17,'TileSpacing','none','Padding','none'); 
nexttile

It works. Thanks!

Here are a couple of 3rd party codes posted in MATHWORKS that can be used to get a better view of subplot figures by tightening the spaces between plot figures
