If I have an array 397x596 size filled with 1 and 0, is there a method where I could generate a random coordinate of the array that has element of 0?
So far I have used [row, column] = find(house == 0); to find the coordiantes containing 0

Well, you're almost there.
just pick a random pair from row and column
% i'm just generating a random house here
house = rand(397,596) > 0.5;
% your code to find indices of elements that are zero
[row, column] = find(house == 0);
% go ahead and pick one of those indices
n = randi(length(row));
row_coord = row(n);
col_coord = column(n);
Cheers
Manuel
