low quality figure problem when saving as svg or pdf ( using fill function)

Hello,
I tried to look through this problem but couldn't find a solution, maybe I am missing something.
The problem happens when creating a figure with "fill" function. When the inputs are small matrices there is no problem and I can get high res images both in svg and pdf format however when bigger matrices are used image gets pixelated and blurry.
A simple example is as follows:
x=rand(10,10);
y=rand(10,10);
z=rand(10,10);
figure,axis equal,
fill(x,y,z)
x1=rand(50,50);
y1=rand(50,50);
z1=rand(50,50);
figure,axis equal,
fill(x1,y1,z1)
When saving those figures in svg or pdf format I get this problem. The figure created using 50x50 matrix becomes low quality.
Did anyone come upon this problem? I would appreciate if somebody points methe right direction.

This issue occurs when the figure is quite complex, like your second one. One solution is to force a vectorised export by going to, in your figure window, File > Export Setup... > Rendering (under Properties) > select 'Custom renderer' and 'painters (vector format)' from the dropdown list > Export > save it as svg or pdf as you wish.
NB: it may take a while to generate, and the background colour to the figure window will turn white while it is doing so.

How is the quality different? My saved pdf looks just the same.
x=rand(10,10);
y=rand(10,10);
z=rand(10,10);
figure,axis equal,
fill(x,y,z)
x1=rand(50,50);
y1=rand(50,50);
z1=rand(50,50);
figure,axis equal,
fill(x1,y1,z1)
saveas(gcf,'myfigure.pdf');
