Ok, I'm having a big problem as described here: http://www.physicsforums.com/showthread.php?t=46950
Basically, I've never used matlab and was given an assignment on friday which requires that I use matlab. First off, could someone please help me with my projectile problem? Next, how the heck does one write an mfile. I know how to open the editor and the simple stuff but actually using ODE45 is killing me. The help file is about as useful as a man filegood for pro's lousy for novices. Any help would be greatly appreciated.

If you haven't already figured it out, there's nothing much to an .m file. Since i do not warez matlab, i'm using vim (a text editor) and octave. Basically what goes in a .m file is something like this

Dont know about the projectile project but with the m  file i could help...
open a new mfile which can be found in File, then New... after which click on Mfile... Here u type in your code... when your done save it and give it a name (obviously... hehehe) now u can call your Mfile from the command window in the main page... however, if u want to make your own functions, wherein a created mfile will act like a regular function in matlab... all the functions in the matlab library have mfiles as well... search for function in help to get details... to see what im talking about type this: type specgram upon pressing enter, the entire code will come up... thats basically the same thing u need to do... the help for function is fairly easy to use... hope i helped!
