oop - creating rational class constructor in matlab -

-

Suppose we have the following category, I want to declare a rational number square in the matab, I'm going to do object-oriented programming in matlab languages. And I want to learn the basic 
  classdef ratnum% rational number class properties (access = protected) n% fraction% d% denoter end methods work r = ratnum (fraction, denomenator) = fraction; R.d = denomenator; End end   
 How can I create a constructor with specific values ​​in the matlab body? Should I use the class name? Thanks in advance   
 
 
 You can use it to instantate the object of this class:  MATLAB does not have the overloading method that is based on the quantity of input passed, you can select  nargin  to select the correct position   
 / Code> can be used:  
  classdef ratnum% rational number class properties (entry = protected) n% / fraction number d% // interval end methods work R = rattanam Sh, denominator) switch Nargin Case 2 RN = digits; R.d = divisor; Case 0% // Whatever you want for end-end ending   
 is a simple debug move  num1_str = struct (num1)  which allows you to To view the object's content, however, you should create some public methods (instead of changing the object to  struct  each time) to get value.  
 
 To overload the MATLAB's default equation, it is necessary to understand that whenever you type  a + b , its automatic translation is  plus ( A, B) . When defining custom sections with custom equations, you should create a folder containing the name  @classname  (in your case  @ratnum ) and in:  < Ul> 
  •   ratnum.m : class definition file (which is the code you have written)  
  •  A file named  plus.m  whatever Looks like:   
      
      function sum = plus (ratnum1, ratnum2) ratnum1 = ratnum (ratnum1); Ratanam 2 = Ratnam (Ratanam 2); Yoga = (... Ratanam 1. R * Ratanam 2D ​​+ ... Ratnamam 2. R * Ratanam 1D) / ... (Ratanam 1D * Ratnam 2D);   
     Then, when you add  +  to  Ratnam  s, it will use the right plus function.  
     Here are some useful readings:  
     
     In order to call class methods, in addition to other class methods, you must always enter the first name : Ratnum.sum (ratnum1). Here is an example:  
      classdef ratnum% rational number class properties (access = public) n% // fraction d% // interval end methods (entry = public) function r = ratnum (fraction , Negotiator) Switch Nargin Case 2 RN = fraction; R.d = divisor; Case 0% Whatever you want for end-of-the-end methods (access = public, static) = Sum (Ratanam) out = Rotum. N + ratamnam d; End end   
     then:  
      & gt; & Gt; A = Ratnam (1,1) A = Ratanam with qualities: N: 1D: 1> & Gt; Ratnum.sum (a) ans = 2

    ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

    -
    I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

    Matlab transpose a table vector -

    -
    An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

    c# - Textbox not clickable but editable -

    -
    I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
