I want to plot 2 things side by side but at a fixed aspect ratio of 4:3. Is there a way to do this?

Hi
You use "subplot" function to draw two figures side by side and set the aspect ratio of each figure by using "pbaspect".
x = linspace(0, 2*pi, 100);
y1 = sin(x);
y2 = cos(x);
figure;
% Plot the first subplot
subplot(1, 2, 1);
plot(x, y1);
title('Sine Wave');
pbaspect([4 3 1]);
% Plot the second subplot
subplot(1, 2, 2);
plot(x, y2);
title('Cosine Wave');
pbaspect([4 3 1]);
Refer to the below documentation for the detailed instrutctions on how to use "pbaspect" function.

Ran in:
you could use pbaspect on each subplot
figure;
ax1=subplot(2,1,1);
plot(rand(10,1));
ax2=subplot(2,1,2);
plot(rand(100,1));
% run on each axis
arrayfun(@(in) pbaspect(in,[4 3 1]),[ax1 ax2])
% instead of saving each axis, you could collect all of the current figure after creation:
f=figure;
subplot(2,1,1);
plot(rand(10,1));
subplot(2,1,2);
plot(rand(100,1));
% run on each axis
axs=findall(f,'type','axes');
arrayfun(@(in) pbaspect(in,[4 3 1]),axs)
