avg - average (arithmetic) mean of values
SYNOPSIS
avg(x_1, x_2, ...)
TYPES
x_1, ... arithmetic or list
return as determined by types of items averaged
DESCRIPTION
If there are n non-list arguments x_1, x_2, ..., x_n,
for which the required additions and division by n are defined,
avg(x_1, x_2, ..., x_n) returns the value of:
(x_1 + x_2 + ... + x_n)/n.
If the x_i are real, the result will be a real number; if the
x_i are real or complex numbers, the result will be a real or complex
number. If the x_i are summable matrices the result will be a matrix
of the same size (e.g. if the x_i are all 3 x 4 matrices with real
entries, the result will be a 3 x 4 matrix with real entries).
If an argument x_i is list-valued, e.g. list(y_1, y_2, ...), this
is treated as contributing y_1, y_2, ... to the list of items to
be averaged.
EXAMPLE
; print avg(1,2,3,4,5), avg(list(1,2,3,4,5)), avg(1,2,list(3,4,5))
3 3 3
; mat x[2,2] = {1,2,3,4}
; mat y[2,2] = {1,2,4,8}
; avg(x,y)
mat [2,2] (4 elements, 4 nonzero):
[0,0] = 1
[0,1] = 2
[1,0] = 3.5
[1,1] = 6
LIMITS
The number of arguments is not to exceed 1024.
