Plotting Piece-wise like function

1 view (last 30 days)
Hey, I am new to MATLAB and to coding overall, so it should be an easy question answer, but still I am having some trouble. I have to plot agraph that is y=2x from 0 to 3 and y=2.5x from 3 to 4. (The graph I am adding is like what I am trying to plot). The thing is that I can not use commands like piece-wise because I'm using octave for MATLAB language. Thanks in advance.

The graph you have shown should be discontinuous at x=3

You can use hold to plot multiple graphs in the same figure. This way you can graph any picewise function:
x1 = 0:3;
x2 = 3:4;
y1 = 2*x1;
y2 = 2.5*x2;
plot(x1, y1);
hold on
plot(x2, y2);
hold off
