Random array Coordinates for certain elements

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);
