Hello!
While tthe exact dimensions of the plot axes cannot be specificed, you can set up the relative aspect ratio of the axes lengths using the "pbaspect" function.
A=rand([10 1]).*10;
B=rand([10 1]).*10;
plot(A,B)
pbaspect([12.1 11.1 1])
You may refer to the following documentation to learn more: https://www.mathworks.com/help/matlab/ref/pbaspect.html.
Hope this helps!
