Hi Leon,
I understand that you want to export a figure which is a combination of multiple axes, as a pdf of A4 size. Refer the following pointers for better understanding:
- You are working with R2019b and you can use 'tiledlayout()' function to combine multiple axes together into a common figure. Refer the following documentation for more details: https://www.mathworks.com/help/releases/R2019b/matlab/ref/tiledlayout.html
- Below is a sample code for exporting the figure object as a pdf:
f = figure;
tiledlayout(f,1,2);
nexttile;
x = linspace(1,10,2);
y = 2*x + 3;
plot(x,y);
nexttile;
y = 3*x+7;
plot(x,y);
set(f,'Units','Inches');
pos = get(f,'Position');
set(f,'PaperPositionMode','Auto','PaperUnits','Inches','PaperSize',[8, 10])
print(f,'myfigure','-dpdf','-r0','-fillpage')
Note that the values specified for 'PaperSize' in 'set' function should be modified according to the use-case which for you would be the dimensions of A4-size paper.
