| Plot of Damped Harmonic Oscillation in FREEMAT, a simple introduction to programming in FREEMAT software. 1. The little routine runs like this-- t = linspace(-3,3); plot(cos(5*t).*exp(-t),'r-','linewidth',3); grid 2. And after you run this routine from the edit window, the plot with grid will look like this-- 3. Open the dampedharmonicoscillator.m file , and when your little browser window ask you what Program to run the .m file chose Freemat, then go into the bin directory to get the .exe {it will say Freemat}. 4. Marvelous, you will see the Freemat command window in front of your eyes, if you have uploaded and installed Freemat on your computer. {you can download and free as the name implies at http://freemat.sourceforge.net/#download}. 5. Next open the editor by either typing editor in the command window, or under tools select Editor. 6. Once in editor you will see the dampedharmonicoscillator.m file run it with the first green arrow from the left and at the top of the editor window. It is a run or execute buffer button. 7. The plot window will come up and look like the one shown above. |
