MATLAB: Binary data in Logical associated with coordinates

arrayarraysbinarycell arraystext filetext;textscan

I need to export only the 1's in a logical array into a text file. But, I need to export the coordinates associated with the 1's into a text array, not the 1's themselves. Would this be possible?

>> X = randi(2,5)-1;
>> [R,C] = find(X);
>> csvwrite('temp2.txt',[R,C])
produces this file (with the coordinates of the ones):
2,1
5,1
3,2
5,2
3,3
5,3
1,4
2,4
5,4
1,5
2,5
