Problem in find function???

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 =

     1
     3
     2
     4
     1
     3
     4
     2
     4

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

Thank you

[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]

Thank you for your reply

I want to get the columns which contains non zero value only.

I find in each row, so it was OK.
