Dear bros,
I want to find the index of spesific element in a matrix, but I think there is problem
A = [1 0 2 0; 0 3 0 4; 5 0 6 7; 0 8 0 9]
[col, row] = find(A);
A =
1 0 2 0
0 3 0 4
5 0 6 7
0 8 0 9
col =
1
3
2
4
1
3
2
3
4
row = ...
col value is wrong, right ??
I think
col =

3
2
4

Is it bug ??? Do any one can explain to me.

[row,col] = find(A);
First you will get rows and then columns ..
Check:
idx = find(A) ;
[i,j] = ind2sub(size(A),idx) ;
[i j row col]
