How to plot all figures in one plot (like hold on hold off command) using for loop. I don't need 12 subplots. I need 12 figures in one plot.

clc; clearvars; close all;

x=-10:0.1:10;

c=-6:5;

for i=1:length(c)

y=c(i)*x.^(2)+4*x+2;

subplot(3,4,i)

plot(x,y)

xlabel('x')

ylabel('y')

end

Here's one simple way:

x=-pi:0.1:pi;

c=-6:5;

figure

hold on

for i=1:length(c)

y=c(i)*x.^(2)+4*x+2;

plot(x,y)

end

xlabel('x')

ylabel('y')

hold off

Another option, in case all plotted vectors have the same number of elements, is to make y a matrix:

x=-pi:0.1:pi;

c=-6:5;

figure

y=c.*x(:).^2+4*x(:)+2;

plot(x,y)

xlabel('x')

ylabel('y')
