Is it possible to plot multiple equations with different intervals?

If I have three different equations for example y=x, y=x^2, and y=sqrt(x), is it possible to graph them over three different intervals on the same graph. Like y=x is plotted from 0 to a, y=x^2 is plotted a to b, and y=sqrt(x) is plotted from b to c?

Yes.

For example:

x = [linspace(0,5,25);  linspace(5,10,25);  linspace(10,15,25)];
y = [x(1,:);  x(2,:).^2;  sqrt(x(3,:))];

figure(1)
plot(x', y')
grid

produces:

There are probably other ways of doing it, but this works.

Star strider you come through again, thank you!

My pleasure, as always!

Hi, is there a way for the lines to be connected, as in that there is a straight line inbetween them?

[Star Strider]

@Johan Ahlberg — The point here was to not connect them. Connecting them simply requires reshaping the vectors —

x = [linspace(0,5,25);  linspace(5,10,25);  linspace(10,15,25)];
y = [x(1,:);  x(2,:).^2;  sqrt(x(3,:))];

figure(1)
plot(x', y')
grid
xlabel('X')
ylabel('Y')
title('Separated')

xv = reshape(x',1,[]);
yv = reshape(y',1,[]);

figure
plot(xv, yv)
grid
xlabel('X')
ylabel('Y')
title('Connected')
