I want to eliminate the margins of Axes, but it doesn't work.

I tried to remove the left and right margins with the following code, but it did not work.
I have set the width of the OuterPosition minus the margins on both sides of the TightInset to the Position, but the left margin does not disappear. Why is this?
When I moved the plot with the mouse, it was exactly the same width as the figure.
In the attached image, the margins are colored for clarity.
plot(rand(1,20))
ax = gca;
ax.OuterPosition(1)=0;
ax.OuterPosition(3)=1;
ax.Position(3)=ax.OuterPosition(3)-ax.TightInset(1)-ax.TightInset(3);

The "TightInset" includes the tick labels. See https://www.mathworks.com/help/matlab/creating_plots/automatic-axes-resize.html
Try to set the 'Position' property instead:
plot(rand(1,20))
figure('Color', 'y')
ax = gca;
ax.Position(1) = 0;
ax.Position(3) = 1;
