how can i make my plot to stop at point and continue after this point?

i have a matlab assignment that needs a start point and an end point with an obstical between them, i want my path to start from (0,0) and end at (100 100) and the obstical is locatedat (50,50) and it a circle. i want my path to avoid the edge of the circle and continue to (100,100).

its a path of robot that avoids an obstical.

PS im really new to matlab

clear

clc

xs=0;

ys=0;

xg=100;

yg=100;

plot (xs(1), ys(1),'*r');

hold on

plot(xg(1), yg(1),'*b');

r=5;

xo=50;

yo=50;

th = 0:pi/6:2*pi;

xunit = r * cos(th) + xo;

yunit = r * sin(th) + yo;

plot(xunit, yunit);

for n=1:100

plot(n,n,'.k')

if n==45

x

end

end

You can replace some value with NaN. Plot function breaks line at that place

Can you please guide me through it if its not a problem, please. Thank you

Something like that i think

x = linspace(xs,xg,20);
y = linspace(ys,yg,20);
y(10) = nan;
plot(x,y)
hold on
plot(xunit,yunit)
hold off

The result
