How do I change the position of the axes permanently?

Although I keep putting them on origin, the X and Y axes keep going down and left every time I plot a function. So I was wondering if I can change this permanently to have them always on the origin.

What does "keep putting them on origin" mean? What is going to where? Which origin do you mean?

Can you post some code and a screen shot, which explains, what you want to achieve?

This is a bit ambiguous.

One option is to use the axis function.

Another are to set the Axes Properties, specifically XAxisLocation and YAxisLocation.

There are some defaults you can set as defaults, but XAxisLocation and YAxisLocation do not appear to fall under the list of things I can set as defaults for the root. I assume that is because they are axis properties, not figure properties.

However, nothing stops you from writting a little helper function, thus...

function setAxesToOrigin
  set(gca,'XAxisLocation','origin')
  set(gca,'YAxisLocation','origin')
end

Then just execute that function after your plot is done.

Taking a stab at the OP's meaning (thanks to the Crystal Ball having just been returned from the shop (yet) again...)

Try

set(groot,'defaultAxesXAxisLocation','origin')
set(groot,'defaultAxesYAxisLocation','origin')

You have to either hold the axes after setting the axis location or set the axis location after plotting.

ax = subplot(1,2,1);

ax.XAxisLocation = 'origin';
ax.YAxisLocation = 'origin';
xlim([-1,1])
ylim([-1,1])
hold on % <---------  hold axes
plot(rand(1,20)*2-1,rand(1,20)*2-1,'o')

or

ax = subplot(1,2,2);
plot(rand(1,20)*2-1,rand(1,20)*2-1,'o')
xlim([-1,1])
ylim([-1,1])
box off
ax.XAxisLocation = 'origin'; % <----- after plotting
ax.YAxisLocation = 'origin'; % <----- after plotting
