2D random walk sequence

starting at (0,0) sample a random number x1 and x2 that is evenly distributed in the interval (0,1]. step size is s=100ln(x1) and angle alpha=2*pi*x2. move the point by step s and angle alpha.

Answer 1

[Azzi Abdelmalek]

x1=rand(1,10)
x2=rand(1,10)
s=100*log(x1)
alpha=2*pi*x2
c1=s.*exp(j*alpha)
c1_x=cumsum(real(c1))
c1_y=cumsum(imag(c1))
plot(c1_x,c1_y,'->r')
