How to name point on plot?

Hello, I have to plot some points in a graphic. I know that I can mark the points with 'o' or with 'x', but can I rename the points that I plot? For example A1, A2 ecc.

This is my program and how I plot my points.

b1=1;
a2=2;
b2=0.5;
a3=3;
b3=1.5;
a4=2;
b4=2;
p0=2.1;
q0=0.6;
r0=1.5;
p1=2;
q1=2;


sol(:) = fsolve(@(x)funzmia6(x), 1:8);
s0=sol(1);
r1=sol(2);
s1=sol(3);
vxp0=[p0,p1];
vyq0=[q0,q1];
vxr0=[r0,r1];
vys0=[s0,s1];
vxpr=[p1,r1];
vyqs=[q1,s1];
vx00=[p0,r0];
vy00=[q0,s0];
