%Link P4 and P5 x,y cordinates%
axis([-2 2 -2 2])
x4 = [P4(1), P5(1)];
y4 = [P4(2), P5(2)];
plot(x4,y4, 'black','b- .','MarkerSize',20);
hold on

Use this to get the desired output:
plot(x4,y4, "k-s", "MarkerFaceColor","b","MarkerSize",20);
Here:
k- is used to assign black line.
s is used to assign square marker. ( You may try out other markers like * etc )
"MarkerFaceColor","b" is used to assign marker colour.
"MarkerSize",20 is used to assign marker weight.
