How can I transfer values if specific condition is fulfilled?

Hello,

I got a Matrix with different cases:

a= (6,6)
0	1	0	2	0	0
0	2	0	1	0	0
0	1	0	2	0	0
0	1	0	2	0	0
0	1	0	2	0	0
0	2	0	1	0	0

And another matrix with different values:

b=(6,6)
1	3	1	1	3	1
2	4	2	3	4	3
3	5	3	4	5	4
4	6	3	5	6	5
5	5	4	6	5	6
6	6	5	6	6	6

Now I would like to transfer values of second and fourth collum of b [b(x,2)&b(x,4)] into a new Matrix if condition a(x,2) or a(x,4)= 1 is fulfilled.

So the end result would look like this:

c=(6,1)
3
3
5
6
5
6

How can I do this with Matlab? And I would like to keep the order. So it should work from line to line. Not collum for collum.

Thanks for helping me.

A = a.';
B = b.';
B(A==1)

Would this keep the order correct?

I tried it like this. But it goes collum by collum and not line by line...

c=b(a==1)

In my answer, I also added the transpose. That will keep the order correct.

Perfect, it works ! Thanks a lot :)

Glad to be of help.
