How do I plot this?

Hello, I have 3 matrix (Eg: a=[0.1;0.2;0.3;0.4;0.5;0.6;0.7;0.8;0.9;1.0] , b=[0.2;0.3;0.4;0.5;0.6;0.7;0.8;0.9;0.9;0.9], c=[0.4;0.5;0.6;0.7;0.8;0.9;0.3;0.2;0.1]) that I want to plot. How do I go about and plot this with different color indication for a,b and c (Eg: I want a to be blue, b to be red, and c to be yellow).

Try this

plot (a, 'color', 'blue')
hold on
plot(b,'color', 'red')
hold on
plot (c,'color', 'yellow')
hold off

If you want to plot them separately ignore hold on and hold off. You can search for more colors if you need here

Hello! Thank you for the quick response! I have tried the code! It works well.

However, is there a way where I can plot it with dots instead? So I can show each individual points.

Yes you can use dots for example do this for each plot that you need:

plot (a,'.', 'color', 'blue')

you can use many more like '*' or '+', please take a look at this documantation.

Hello! Thank you for the quick response! It works well! I have another question, how do I make the '*' and the labellings bigger in the plot?

[BN]

Hi Yes you can doing this:

p1 = plot (a, '*', 'color', 'blue')
p1.LineWidth= 10;

Change 10 to 12 to bigger and 10 to 8 to smaller font, for example.
