Showing angles around plot in matlab / octave -

-

I can create a plot with pol2cart, but how can I show angles at the end of the lines? See the code below: 

  Hold down; = 0:20 for angle: (360-20) [x1, y1] = poll 2 cart (angle / 180 * p, [0 2]); Plot (x1, y1, 'r') rho = 0: 0.1: 2 end to [x1, y1] = pol2cart (0: 0.01: 2 * pi, rho); Plot (x1, y1, 'b') end axis is equal to

I am trying to show the scale of the angle to see the image below. Please note, to show all the numbered angles only to show what I am trying to do, I did not attract the first couple

PS: I am using Octave 3.8.1 Which tries to use the same language syntax, Matlab ima2

< P>

you can do something like 

  step = 20; R = 2.2; IDX = 0: Step: 360-step text (r * cos (pi * idx / 180), r * sin (pi * idx / 180), num2str (idx), ... 'horizontal alignment', 'center' To optimize,  
  axis (1.05 * [- - - RR - '' color '', [1.55])  
 
 RR]) Include Ax like

(It works for MATLAB, I do not know whether the syntax is the same.)

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...
