I tried this which apparently worked previously but when i try it it doesnt work

>>function y=kastbana(x, theta)

>>t=theta*pi/180; % theta i grader, t i radianer

>>v0=10; y0=1.85; g=9.81;

>>a=g/(2*v0^2*cos(t)^2); b=v0^2*sin(2*t)/(2*g); c=v0^2*sin(t)^2/(2*g);

>>y=y0-a*(x-b).^2+c;

">> kastbana(x,theta)

Unrecognized function or variable 'theta'."

If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks). That might be more effective than posting a question and waiting for a response.

Thanks! I didn't know about that, but I'm just wondering if theres a small mistake I've done here.

Update: I made a new file and typed in the function again and now it worked somehow. I don't know why but anyway. Thanks for the help. What does "doc" do?

The doc command searches the documentation. So running doc function in your command window will open the documentation page for the function keyword. That will contain an explanation about how to use it, and some examples and links.
