else
    perform 4
end

Examples are as follows ：

warning off;

 

Y = 10*rand


if Y>0 & Y<=2;
   B=1 ;
elseif Y>2 & Y<=4;
   B=2 ; 
elseif Y>4 & Y<=6;   
   B=3 ; 
else
  B=4 ;   
end

B

The meaning of this code is , Randomly produce a 0~10 Random number between Y, And then determine Y Size ,

If Y stay 0~2 Between ,B The assignment is 1,

If Y stay 2~4 Between ,B The assignment is 2,

If Y stay 4
