Using MATLAB

Write a script to compute and plot the path of a random walker in a 20 by 20 room (walker starts at the origin; room extends from-10 to 10 in each direction) A random walk is computed by performing the following calculation until the new position is outside the walls, and the walker is "absorbed." xnew xold+0.5* (1-2*rand) ynew-yold+0.5*(1-2 rand) The function rand" in MATLAB returns a "random" number between 0 and 1. For each case, have your code plot the path of the walker and output the number of steps that the walker stays alive. Run 5 different cases and include screen shots in the results section of your MS Word document
