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.
