2 avg - average (arithmetic) mean of values
8 x_1, ... arithmetic or list
10 return as determined by types of items averaged
13 If there are n non-list arguments x_1, x_2, ..., x_n,
14 for which the required additions and division by n are defined,
15 avg(x_1, x_2, ..., x_n) returns the value of:
17 (x_1 + x_2 + ... + x_n)/n.
19 If the x_i are real, the result will be a real number; if the
20 x_i are real or complex numbers, the result will be a real or complex
21 number. If the x_i are summable matrices the result will be a matrix
22 of the same size (e.g. if the x_i are all 3 x 4 matrices with real
23 entries, the result will be a 3 x 4 matrix with real entries).
25 If an argument x_i is list-valued, e.g. list(y_1, y_2, ...), this
26 is treated as contributing y_1, y_2, ... to the list of items to
30 ; print avg(1,2,3,4,5), avg(list(1,2,3,4,5)), avg(1,2,list(3,4,5))
33 ; mat x[2,2] = {1,2,3,4}
34 ; mat y[2,2] = {1,2,4,8}
37 mat [2,2] (4 elements, 4 nonzero):
44 The number of arguments is not to exceed 1024.
