10.8 Reducing and Mapping Vectors

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.
