Random row from matrix with row number Matlab -


Matlab How to choose a random line from the matrix, and the selected number of rows? The designated matrix ICO M is 4x3 as follows: 

  -21.8318 19.2251 -16.0000 -6.2788 8.6988 -10.0000 1.5553 -0.8041 - 2.0000 17.6843 - 13.0848 0.3000   
 Choosing a random line from the matrix  M  is my question simple (which is, in fact, no big deal) with its line number?  1   
 
 
  randi  use  and  M , and then use it in the index in  M :  
  ind = randi (size (m, 1)); % // line number row = m (ind, :); % // related line
