r - Sort rows of matrix according to number of different digits -

-

I have a matrix that contains lines of binary vectors: 

  libraries (gtools) Mat and lieutenant; - Repeats the devices (2,6, V = C (0,1), declares = TRUE)

I would like to sort the rows of the matrix so that each row differs. Only 1 point from your direct neighbors (up and down)

Is this possible?

Interesting questions! The way in which I thought that it was thought of to be done, it is to recapture such matrix with a small number of digits in it. Suppose we have an N-digit matrix (which contains all 2 ^ N unique en-bit sequences) where each neighbor is different in more than one. If we do rbind with its matrix (according to the lines), then each row of the result will be more than 1, and in between the two rows will be equally identical. We can add 1 in front of the first half and 1 in front of the second half. All 2 ^ (n + 1) in the result are unique (n + 1) -bit sequence, and all neighbors have more distance than each other.

For the base case, we (0 1) for 1-digit matrix. 

  get.mat

An interesting side effect for the construction of these matrix is ​​that the first and the last lines are o 1 distance from each other.

winforms - C# Form - Property Change -

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
