Storing Data into a Matrix from a for loop

Hello, I would like to alter my code so that every value for position is stored in a matrix rather than dispaying only the final value so I can plot them later. How would I write this out? Here's what I've got. Thanks!

position = 0;
tails = 0;
heads = 1; 

for s = (1:1000)
   
    x=randi([0 1]);
    
   if x==tails
       position = position-1;
       
   elseif x==heads
       position = position+1;
       
   end
    
end

position = zeros(1,1000);
position(1)=0;
tails = 0;
heads = 1; 
for s = 2:1000
   
    x=randi([0 1]);
    
   if x==tails
       position(s) = position(s-1)-1;
       
   elseif x==heads
       position(s) = position(s-1)+1;
       
   end
    
end

Hello Estevan,

Try this:

position = zeros(1,1000);
tails = 0;
heads = 1; 
for s = (1:1000)
   
    x=randi([0 1]);
    
   if x==tails
       position(s) = position(s)-1;
       
   elseif x==heads
       position(s) = position(s)+1;
       
   end
    
end

Unfortunately doesn't dispaly data correctly.

The orginal data became skewed for some reason.
