The commands in this section allow for more general operations on the elements of vectors.
The simplest of these operations is V A (calc-apply)
[apply], which applies a given operator to the elements of a vector.
For example, applying the hypothetical function f to the vector
‘[1, 2, 3]’ would produce the function call ‘f(1, 2, 3)’.
Applying the + function to the vector ‘[a, b]’ gives
‘a + b’. Applying + to the vector ‘[a, b, c]’ is an
error, since the + function expects exactly two arguments.
While V A is useful in some cases, you will usually find that either V R or V M, described below, is closer to what you want.
