x = [-2:0.1:2];
a = [.5, 1, 1.3, 1.95];
figure;
for i=1:length(a)
z = x.*(a(i)-x.^2);
plot(x,z);hold on;
end

Ran in:
One way is to use rand. Colors here will be choosen randomly
x = [-2:0.1:2];
a = [.5, 1, 1.3, 1.95];
figure;
for i=1:length(a)
z = x.*(a(i)-x.^2);
plot(x,z,'Color', rand(1,3))
hold on;
end
Another way is to use binary vectors -
%this works here as we only 4 graphs to plot
%there are only 8 binary triplets available
x = [-2:0.1:2];
a = [.5, 1, 1.3, 1.95];
figure;
for i=1:length(a)
z = x.*(a(i)-x.^2);
plot(x,z,'Color', dec2bin(i,3)-'0')
hold on;
end

Dear @Dyuman Joshi please if you have idea, I want the command to choose the color of the line and also the type of line (dashed line, dashed ...) and line width.
Thank you
