I'm trying to create a game in MatLab for class project, one of my goals is to use a matrix to create a map, so I need to be able to generate an matrix of numbers that has 2 unique points, either fixed, or randomized, one for the player's starting positon, or spawn point, and one for the ending point as a goal for the character, I know how to create a matrix of random numbers using the rand command, however, I have no idea how to insert 2 unique points and make sure those 2 points are always there

start_pt = [1 3]; % first row, third col
end_pt = [5 1]; % fifth row, first col
M = rand(5); %5x5 random map
M(start_pt(1),start_pt(2)) = some_unique_value;
M(end_pt(1),end_pt(2)) = some_other_unique_value;
is this what youre looking for?

I don't have too much context so I don't really know what to suggest as the most optimal method. What exactly are you randomizing? Are you randomizing INDICES for where the start/end points would be, or are you randomizing the VALUE located at those FIXED indices?
the randi() function could help you here.
