matlab - What is .' appended to end of list for use in bsxfun do? -

An example is given from matlab docs for BSXFun:

  have fun = @ ( A, B) A * sin (B); A = 1: 7; B = P * [0 1/4 1/3 1/2 2/3 3/4 1]. '; % What is it .' So am I? C = BSXFun (funny, A, B)   
 I understand how BSX is used, but I do not understand. Does? I understand that 'to move, but what is it?'   
 
 
 Did you know that you can type things  help /  Or  support. ? You will find help for all MATLAB operators and special characters.  
 To get help on  Transfer , you should first know something about the MATLAB syntax.  
 To protect yourself  
 To transpose the vector:  
 This is a strange object in which apostrophs play the triple roll:  
 
 / matrix   
 The second allows you to type a letter letter inside a string:  
  & gt; & Gt; A = 'How it is done!';   
 This third role is due to historical reasons, and in my opinion it is rather unfortunate. Because, if you try  
  & gt; & Gt; help .'   
 The MATLAB syntax rules dictate that it  
  & gt; & Gt; Help ('.' ')   
 Which is an  unexpected string  Therefore, to get help on transposes, you have to "escape" Apostrophy:  
  & gt; & Gt; Help please ''   
 What answer does you give:    ... move - transjections. 'Ctranspose - Complex conjugate infection' ...   
 So this is the difference:  
  & gt; & Gt; A = [1 + 1i 2 + 2i 3 + 3E4 + 4i]; & Gt; & Gt; A 'ans = 1.0000 - 1.0000i 3.0000 - 3.0000i 2.0000 - 2.0000i 4.0000 - 4.0000i & gt; & Gt; a.' Ans = 1.0000 + 1.0000i 3.0000 + 3.0000i 2.0000 + 2.0000i 4.0000 + 4.0000i   
 Here are some fun things you can do:  
  & gt; ; & Gt; A 'A.' Answer = 14 30 20 44   
 Of course, you could get help with  assisted transmitted  or  help ctranspose  Apostrophe-Notation is the only nickname for those long function names. When you are going to OOP and operator overloading, then the names of those long functions are also used:  
  classdef MyAwesomeClass methods% // How to overload the Transceppe operator for your class Is: apply obj = transpose (obj)% // here end end end
