Functions and commands 401

Example:

matpow([[1,2],[3,4]],n) gives [[(sqrt(33)-

3)*((sqrt(33)+5)/2)^n*-6/(-12*sqrt(33))+(-

(sqrt(33))-3)*((-(sqrt(33))+5)/2)^n*6/(-

12*sqrt(33)),(sqrt(33)-3)*((sqrt(33)+5)/

2)^n*(-(sqrt(33))-3)/(-12*sqrt(33))+(-

(sqrt(33))-3)*((-(sqrt(33))+5)/2)^n*(-

(sqrt(33))+3)/(-

12*sqrt(33))],[6*((sqrt(33)+5)/2)^n*-6/(-

12*sqrt(33))+6*((-(sqrt(33))+5)/2)^n*6/(-

12*sqrt(33)),6*((sqrt(33)+5)/2)^n*(-

(sqrt(33))-3)/(-12*sqrt(33))+6*((-

(sqrt(33))+5)/2)^n*(-(sqrt(33))+3)/(-

12*sqrt(33))]]

MAXREAL Returns the maximum real number that the HP Prime is

capable of representing: 1.79769313486*10

308

mean Returns the arithmetic mean of a list (with an optional list as a

list of weights). With a matrix as argument, returns the mean

of the columns.

mean(List1, [List2]) or mean(Matrix)

Example:

mean([1,2,3],[1,2,3]) gives 7/3

median Returns the median of a list (with an optional list as a list of

weights). With a matrix as argument, returns the median of

the columns.

median(List1, [List2]) or median(Matrix)

Example:

median([1,2,3,5,10,4]) gives 3.0

member Given a list or vector and an element, returns the index of the

first occurrence of the element in the list or vector; if the

element does not appear in the list or vector, returns 0. Similar

to contains, except that the element comes first in the

argument order.

member(( Element, List) or contains(Element,

Vector)

Example:

member(2, {0,1,2,3}) returns 3

MINREAL Returns the minimum real number that the HP Prime is capable

of representing: 2.22507385851*10
