Create figures with different number of images but same sizes

I try to create 2 figures in 2 different scripts.

Script 1 looks like this:

img_sos = rand(64);
img_oar_pixel = rand(64);
img_oar_block = rand(64);

img_sos = img_sos / max(img_sos(:));
img_oar_pixel = img_oar_pixel / max(img_oar_pixel(:));
img_oar_block = img_oar_block / max(img_oar_block(:));

f = figure;
tl = tiledlayout(1, 3, 'TileSpacing', 'compact', 'Padding', 'compact');

clim1 = [0 1];
cmap1 = jet;
ax1 = [];

ax1(1) = nexttile;
imagesc(img_sos, clim1);
axis image off;
title('Sum-of-Squares', 'FontSize', 10);

ax1(2) = nexttile;
imagesc(img_oar_pixel, clim1);
axis image off;
title('Adaptive Kombination (Pixelweise)', 'FontSize', 10);

ax1(3) = nexttile;
imagesc(img_oar_block, clim1);
axis image off;
title('Adaptive Kombination (Blockweise)', 'FontSize', 10);

set(ax1, 'Colormap', cmap1);
cb1 = colorbar(ax1(end), 'eastoutside');
cb1.Label.String = 'Normierte Signalintensität';
cb1.Label.FontSize = 10;
cb1.Ticks = 0:0.2:1;

My second script looks like this:

figure; %<---Matt J added

img_oar_rec = rand(64);
img_oar_rec = img_oar_rec/max(img_oar_rec(:));
img_mask = rand(64);

tiledlayout(1, 2, 'TileSpacing', 'compact', 'Padding', 'compact'); 

ax1 = nexttile;
imagesc(img_oar_rec, [0 1]);
axis image off;
colormap(ax1, 'jet');
cb = colorbar;
cb.Label.String = 'Normierte Signalintensität';
cb.Label.FontSize = 10;
title('Adaptive Kombination', 'FontSize', 10);

ax2 = nexttile;
imagesc(img_mask);
axis image off;
colormap(ax2, 'gray');
title('Binäre Maske', 'FontSize', 10);

As I want to use these figures in a latex report, I want to save these figures as jpg.

But in both figures, the images should have the same size. Same for the titles and colorbar strings.

How can I do that? I should not scale figures in latex.

What's wrong with the code as is? The images (within each figure) look the same size to me.

If you mean you want a common image size across all axes in both figures, I think the best that you can do is relocate both layouts to a common master figure. The relocation can be done automatically, as below.

You can then make cropped copies of the master figure in MSWord or PowerPoint to achieve separate figures.

%% Create initial figures

tl1=fig1();

tl2=fig2();


%% Relocate to master figure
figure('Position',[ 34         137        1245         813]);

ax=[flip(tl1.Children);flip(tl2.Children)];
ax=findobj(ax,'Type','axes');

TL=tiledlayout(2,3,'TileSpacing', 'compact', 'Padding', 'compact');
for i=1:numel(ax)
 ax(i).Parent=TL;
 ax(i).Layout.Tile=i;
end
close([tl1.Parent,tl2.Parent])

function tl=fig1()

    img_sos = rand(64);
    img_oar_pixel = rand(64);
    img_oar_block = rand(64);
    img_sos = img_sos / max(img_sos(:));
    img_oar_pixel = img_oar_pixel / max(img_oar_pixel(:));
    img_oar_block = img_oar_block / max(img_oar_block(:));

    f = figure;
    tl = tiledlayout(1, 3, 'TileSpacing', 'compact', 'Padding', 'compact');
    clim1 = [0 1];
    cmap1 = jet;
    ax1 = [];
    ax1(1) = nexttile;
    imagesc(img_sos, clim1);
    axis image off;
    title('Sum-of-Squares', 'FontSize', 10);
    ax1(2) = nexttile;
    imagesc(img_oar_pixel, clim1);
    axis image off;
    title({'Adaptive Kombination';'(Pixelweise)'}, 'FontSize', 10);
    ax1(3) = nexttile;
    imagesc(img_oar_block, clim1);
    axis image off;
    title({'Adaptive Kombination';'(Blockweise)'}, 'FontSize', 10);
    set(ax1, 'Colormap', cmap1);
    cb1 = colorbar(ax1(end), 'eastoutside');
    cb1.Label.String = 'Normierte Signalintensität';
    cb1.Label.FontSize = 10;
    cb1.Ticks = 0:0.2:1;


end


function tl=fig2()


    figure; %<---Matt J added
    
    img_oar_rec = rand(64);
    img_oar_rec = img_oar_rec/max(img_oar_rec(:));
    img_mask = rand(64);
    
    tl=tiledlayout(1, 2, 'TileSpacing', 'compact', 'Padding', 'compact'); 
    
    ax1 = nexttile;
    imagesc(img_oar_rec, [0 1]);
    axis image off;
    colormap(ax1, 'jet');
    cb = colorbar;
    cb.Label.String = 'Normierte Signalintensität';
    cb.Label.FontSize = 10;
    title('Adaptive Kombination', 'FontSize', 10);
    
    ax2 = nexttile;
    imagesc(img_mask);
    axis image off;
    colormap(ax2, 'gray');
    title('Binäre Maske', 'FontSize', 10);

end

"... I think the best that you can do is relocate both layouts to a common master figure. "

Couldn't you achieve the same effect in two figures by using the 1,3 layout for each figure so wouldn't have to edit later separtely?

OP's original first has an issue in that the titles are in too large a font for the available room and overlap...either have to cut down the font or shorten the title or wrap text or...

[Matt J]

I don't think so. tiledlayout has strange, opaque rules for determining axis sizes. They would be difficult to sync across separate figures.

[dpb]

Differences probably come from the size of label fields; perhaps if controlled the format to be consistent across all...

[Matt J]

Go for it, but I think it'll be more trouble than it's worth.
