Source code

Made with the following Python script (needs Matplotlib): 

from pylab import *
from random import choice
numwalk = 8
length = 100
data = zeros((numwalk, length), int)
for n in range(numwalk):
	for x in range(1, length):
		step = choice([-1, 1])
		data[n,x] = data[n,x-1] + step
	plot(range(length), data[n,:])
xlabel('t')
axis ((0,100, -20, 20))
savefig('Random_Walk_example.svg')

The following is the similar code in MATLAB and Octave

function RandomWalk () hold off; x = 1:100; color = ['y' 'g' 'b' 'k' 'r', 'm' 'c']; y(1)= 0; for m = 1:7 for n = 2:100 y(n) = y(n-1) + 2*floor(rand()*2)-1; end plot(x, y, color(m), 'LineWidth',2); hold on axis([0 100, -20 20]) end end
