plotting comlex numbers,use one plot command, and each point should be different color

z = [complex(2,5),complex(1/5,3/5),(2+i)^3,(1+i)*(1-3*i),complex(5,-12),complex(-3,0),complex(0,2),complex(1,2*sqrt(2)),complex(-0.59,-0.81),complex(5.9,9.15),complex(sqrt(2),sqrt(2)),complex(-3.07,6.72)]

hold on;

grid on;

C = ['y';'m';'c';'r';'g';'b';'w';'r'];

for x = 1:8

plot(z(x),C(x))

end

xlabel("real part");

ylabel("imaginary part");

axis equal;

this is giving me a blank graph with grids. Somone please help.

z =[complex(2,5),complex(1/5,3/5),(2+i)^3,(1+i)*(1-3*i),complex(5,-12),complex(-3,0),complex(0,2),complex(1,2*sqrt(2)),complex(-0.59,-0.81),complex(5.9,9.15),complex(sqrt(2),sqrt(2)),complex(-3.07,6.72)];
C=['y';'m';'c';'r';'g';'b';'w';'r';'y';'m';'c';'r'];
for x=1:length(z)
scatter(real(z(x)),imag(z(x)),C(x),'filled');
hold on;
end
grid on;
xlabel("real part");
ylabel("imaginary part");
axis equal;

OR You can avoid the for loop also

z =[complex(2,5),complex(1/5,3/5),(2+i)^3,(1+i)*(1-3*i),complex(5,-12),complex(-3,0),complex(0,2),complex(1,2*sqrt(2)),complex(-0.59,-0.81),complex(5.9,9.15),complex(sqrt(2),sqrt(2)),complex(-3.07,6.72)];
real_z=real(z);
imag_z=imag(z);
%% Now plot real_z & imag_z with scatter plot (multi color)

grid on;
xlabel("real part");
ylabel("imaginary part");
