randomwalk - create random walk in arbitrary dimension
P = randomwalk(N, D) produces a N-by-D matrix P with the positions of a random walk of N steps in D dimensions, starting from (0,..,0). P(K,:) holds the coordinates of the position at step K. Each step from one position to the next is +1 or -1 along a random dimension.
With a third logical argument, randomwalk(N, D, true) creates a plot of the random walk in a new figure.

Examples:
P = randomwalk(2, 10) % -> for example
% P = [0 0 ; 1 0 ; 1 1 ; 2 1 ; 2 0 ; 2 -1 ; 3 -1 ; 3 -2 ; 2 -2 ; 2 -1]
randomwalk(1000,4,true) ; % create a plot
