SAS IML Statment

Sanscrit_2prov — Mon, 05 Apr 2021 21:33:59 GMT

Can anyone tell me what this statement is doing?

pot = 2 ## ( (n-1):0 );

If n is 3 it creates pot that equals 4 2 0.

But I don't understand the (n-1):0 indexing

The colon creates a vector of values, from (in your case) n-1 all the way down to 0, by 1.

So when n=3, this produces a vector with values

2 1 0
