Computational Physics Video 29 - Generating Random Walks using MATLAB

[@Hadis_Diaries]

I think the answer of the question in the end of the video is: theta = acos(1-2*rand()).

guys please i could not understand how did he assume the right equations for dx dy dz in 8:10

How about Biased Random Walk? What is the different?

[@DeepaliSingh]

Well, I'm assuming, by biased random walk, you mean the movement in the two directions is not equally probable. Say, probability of going left is .25 and going right is .75. What you do is, generate a random number between 0 and 1. If it's less than .25, ask the particle to go left and right if it's otherwise. :)

I am sorry but you are wrong i believe !! Your sphere looks like and ellipsoid because by default, axes in MATLAB are not equal. So, you have to use command axis('equal'); I have tried it and it works !!
