Why is my code not plotting anything?

x = 1:0.1:10;
y=x.^2;
plot(x,y);

I wrote the above simple code, but when I save this code in a script, it doesn't work when I press the green run button. However if I type it in the command window, it runs fine. Can someone please help me with this. (I am on a Mac.)

It works for me on Mac, in the same release as you used.

But exactly what filename did you use when you saved it as a script ?

It is necessary to save the script as a .m file first, and the MATLAB Editor should have popped up the Save As window when you pressed the green Run arrow if you had not already saved that script. (It did just now when I attempted to do exactly what you describe, in R2021a.)

@Star Strider, do you have a mac? Because I did it on a Windows 10 system and it worked just fine, just as expected.

Win 10, latest updates.

When I copied it to a new script, then clicked on the green Run arrow, the Save As window popped up, telling me to save it first (with the default ‘Untitled.m’). Then it ran without error.
