Reducing Whitespace for a 2x3 subplot

I am trying to reduce the whitespace between a 2x3 grid of images.

I have tried subplot and tiledlayout--codes and images below--apparently to preserve scaling, the spacing and padding options for TiledLayout does not work.

I would greatly appreciate any pointers on reduce the white space between the 6 images (in a 2x3) plot

figure;
subplot(2, 3, 1);
imshow((An{1})); title('$A_{50}$',FontSize=16,Interpreter='latex')
subplot(2, 3, 2);
imshow((An{2})); title('$A_{100}$',FontSize=16,Interpreter='latex')
subplot(2, 3, 3);
imshow((An{3})); title('$A_{200}$',FontSize=16,Interpreter='latex')
subplot(2, 3, 4);
imshow((An{4})); title('$A_{300}$',FontSize=16,Interpreter='latex')
subplot(2, 3, 5);
imshow((An{5})); title('$A_{400}$',FontSize=16,Interpreter='latex')
subplot(2, 3, 6);
imshow((An{5})); title('Original',FontSize=16,Interpreter='latex')
sgtitle('The title',FontSize=16,Interpreter='latex')

 figure;
tiledlayout(2,3,"TileSpacing","none",Padding="tight")
imshow((An{1})); title('$A_{50}$',FontSize=16,Interpreter='latex')
nexttile
imshow((An{2})); title('$A_{100}$',FontSize=16,Interpreter='latex')
nexttile
imshow((An{3})); title('$A_{200}$',FontSize=16,Interpreter='latex')
nexttile
imshow((An{4})); title('$A_{300}$',FontSize=16,Interpreter='latex')
nexttile
imshow((An{5})); title('$A_{400}$',FontSize=16,Interpreter='latex')
nexttile
imshow((A)); title('Original',FontSize=16,Interpreter='latex')

Anything tighter than that obtained with the named parameters you'll have to create by either adjusting the axes 'Position' property after creation or create them manually from the git-go with axes

i think the issue is not with tiledlayout - in my experience "tight" is "really tight"...i think the issue is that since your tiles contain images, and imshow may be doing something independently to preserve aspect ratio and/or scale...for example, if you resize the figure and adjust its aspect ratio, do you find a point where the images fill up the space better?
