I am working on a function the creates a "maze" or NxN array of strings "0". The goal is to move a player "P" in the array randomly through the maze until the player reaches the exit "E" How do i randomly assign an index on the edge of the array the value "E" to represent the exit of the maze?
ex. I need it to look like this
"0" "0" "0" "0"
"0" "0" "0" "0"
"P" "0" "0" "0"
"0" "0" "0" "E"
where "E" is randomly assigned but needs to be on the edge of the array

Z=false(N);
Z(:,[1,N])=true; Z([1,N],:)=1;
I=find(Z);
n=numel(I);
idx=I(randperm(n,2));
Maze(1:N,1:N)="0" ;
Maze(idx(1))="P";
Maze(idx(2))="E"

If you already have a Maze with a pre-placed "P", then modify as follows:
Z=false(N);
Z(:,[1,N])=true; Z([1,N],:)=1;
Z(Maze=="P")=0;
I=find(Z);
idx=I(randperm(numel(I),1));
Maze(idx)="E"
