194 Functions and commands
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 calculator
is capable of representing in Home and CAS views:
In the CAS, MAXREAL=1.79769313486*10
308
In Home view, MAXREAL=9.99999999999E499
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
