How to convert row and column data into x,y,flag format?

I want to store row and column data for BW1 file.

Data is stored in an array like so:

I want to have a file like:

X Y FLAG

1 1 0

2 1 1

3 1 1

4 1 0

5 1 1

1 2 0

2 2 1

3 2 0

4 2 1

5 2 0

X corresonds to column number.

Y corresonds to row number.

Flag number is the number already stored in the array corresponding to the row and column number.

Code:

A=imread('inismor1.jpg');
G=rgb2gray(A);
BW1=edge(G,'canny');
imshow(BW1)
