Next, we store the edited expression into variable
@@@G@@@:
Evaluating G(L1,L2) now produces the following result:
As an alternative, you can define the function with ADD rather than the plus
sign (+), from the start, i.e., use
DEFINE('G(X,Y)=(X ADD 3)*Y') :
You can also define the function as G(X,Y) = (X--3)*Y.
Applications of lists
This section shows a couple of applications of lists to the calculation of
statistics of a sample. By a sample we understand a list of values, say, {s
1
,
s
2
, …, s
n
}. Suppose that the sample of interest is the list
{1, 5, 3, 1, 2, 1, 3, 4, 2, 1}
