Sequences for a 3D matrix

It is possible to find sequences over the 3rd dimension for each element in Matlab? Lets say I have these matrix 3x3x5

            1 1 0  
A(:,:,1) =  0 0 1   
            1 1 1   
            
            1 1 0  
A(:,:,2) =  0 0 1   
            1 0 1 
            
            0 0 0  
A(:,:,3) =  1 1 0   
            0 0 0 
            
            1 0 0  
A(:,:,4) =  1 0 1   
            1 1 1 
            
            1 1 1  
A(:,:,5) =  0 0 1   
            0 1 0 

Now I want to finde sequneces lets 1's two time in a row over the 3rd dimension, so I get the result:

            2 1 0  
result =    1 0 2   
            1 1 1 

Antway to do that?

Answer 1

[Matt J]

  k=ones(1,1,2)/2;
  result = sum(  convn(A,k,'valid')>.999 ,3 );

Where are you putting the value in the sum you want to find the sequence with?

[Matt J]

In general, it would be,

k=ones(1,1,N)/N;

Answer 2

[Andrei Bobrov]

k = reshape([1,1,0],1,1,[]);
result = sum(convn(A,k,'same')==2,3);

[Jonas Damsbo]

If now the value I want to find a sequnece for must be >10. How did I do that?
