one dimensional random walk model MATLAB code??

A drunk man's random walk in one dimension

[Chris McComb]

Many people will be happy to help you with specific MATLAB related questions, but its unreasonable to ask for a full solution to what sounds like a homework question.

hi i am not sure this code is what you want.|

if true
 y=0;
i=1;
while 1>0
  a=sign(randn);
  y(i+1)=y(i)+a;
 pause(.00005);
  plot(y)
i=i+1;
end
end

How often does he take a step? When does he go to sleep? What was he drinking?

The most I can do is to offer up these two attached random walk demos that I've posted before (and you've probably already found if you've done a search of this forum). Feel free to adapt them to 1D by getting rid of the "y" calculation. If you have specific questions with your code, read these:
