My program isn't plotting anything

I made a program meant to plot two arrays in an elipse like graph, but nothing is showing up when i call the plot function. I made sure the function is outside of my loops like so, yet nothing is showing up, what am I doing wrong?
for i=1:360
x1(i)=a;
y1(i)=b;
end
plot(x1,y1)

I’m assuming your variables a and b are actual values. If not, it will obviously give an error that a and b are undefined. I think you have the visibility of your figure turned off. Also I would rename your variable from i to ii in order to avoid confusion with the built in identity of i=sqrt(-1). Try this:
close all
fig=figure;
fig.Visible='on';
for ii=1:360
x1(ii)=a; %a should be some number
y1(ii)=b; %b should be some number
end
plot(x1,y1)

All of your x are the same, and all of your y are the same. You are drawing a line from a point to itself over and over again. That would create at most one dot on the screen. You could add '-*' as a plot option to make the one point more obvious.
