Generate 100 data randomly, or select if it is possible

问题

I want to test my model , I need to test it in some data , I want to generate data , in fact I want to have 125 different parameter from 0 to 10000.

For example , in below we have 4 different parameter ,from 1 to 300.

 Set I/0*300/;
 Parameter MyParameter;
 MyParameter /4 1,10 1,42 1,87 1/;

I don't want to do this by hand.

Is there any method that I generate it automaticly.

another way asking:

how can Select 4 random element of a set ' I' , without repetition?

回答1:

Try this:

Set       I     /0*300/
          picks /p1*p4/;
Scalar    pick;
Parameter MyParameter(I);

MyParameter(I) = 0;
loop(picks,
  pick = uniformInt(1, card(I));

* Make sure to not pick the same one twice
  while(sum(I$(pick=ord(I)),MyParameter(I))=1,
    pick = uniformInt(1, card(I))
    Display 'here';
  );

  MyParameter(I)$(pick=ord(I))=1;
);
Display MyParameter;
