Can I do max filter on a sub_blocks with matlab -


For example, I have a 4x4 matrix, I want to divide it into a maximum of 2x2 sub_regions. And maximize the sub-limit 

  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 \ 6/6, 6, 8, 8, 6, 8, 8, 14, 14, 16, 16, 14, 14, 16, 16    
 
 
 Do you need this suite?  
 (Suppose your data is in the matrix, which is called  M )  
  & gt; & Gt; Cellphone (@ (x) max (x), matcelcel (m, [2 2], [2 2])) ans = 6 8 14 16   
  edit Do:   
 You may also be able to get your desired output:  
  & gt; & Gt; Cron (selphon (@ (x) max (x), matcelcells (m, [2 2], [2 2]), ones (2)) a = 6 6 8 8 6 6 8 8 14 14 14 16 16 14 14 16 16

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
