Please would you explain what you mean by coordinate? How does it differ from the index that the answer to your earlier question gives you?

If you want to specify a question, please either add a comment to the answer or edit the question. Postinmg another thread is worse, because now we have to waste time for searching your earlier question to avoid the creation of an identical answer.
As David has asked already: What is the difference between "coordinate" and "index"?

A=boolean(2*rand(10,10)>1) % Creating a random Matrix
Row = 2; % Assumung you are looking for the first 0 of the row 2.
Colomn = min(find(A(Row,:)))
Coordinates: [Row Colomn]
