2D Random path within a unit square

Hi all, I want to generate a random path within a unit square and get the x,y coordinates of n=1000 points on it. start point and the end point can be picked up from the vertices of the unit square, i.e, (0,0), (0,1),(1,0),(1,1).
The code I have up to now is given as follows. But it does not restrict the path to lie inside the unit square. How can I solve this?
n=1000;
mypath = rand(n,2);
xp=mypath(:,1);
xp_s=cumsum(xp);
yp=mypath(:,2);
yp_s=cumsum(yp);
plot(xp_s,yp_s)

n=1000;
mypath = rand(n,2);
m = cumsum(mypath);
mout = m./m(end,:); % MATLAB >= R2016b
mout = bsxfun(@rdivide,m,m(end,:)); % MATLAB < R2016b

I have a number of random walk demos and I've attached them. Feel free to use them however you wish.

In your loop, simply don't add the next random step if it would take you outside the unit box. Just get another step instead.
