) ⇒
⇒⇒
⇒
matrix
Returns the maximum of the two arguments. If
the arguments are two lists or matrices, returns a
list or matrix containing the maximum value of
each pair of corresponding elements.
max(2.3,1.4) ¸ 2.3
max({1,2},{

max(
list
) ⇒
⇒⇒
⇒
expression
Returns the maximum element in
list
.
max({0,1,ë 7,1.3,.5}) ¸ 1.3
max(
matrix1
) ⇒
matrix
Returns a row vector containing the maximum
element of each column in
matrix1
.
Note: See also
fMax() and min().
max([1,ë 3,7;ë 4,0,.3]) ¸
[1 0 7]
mean() MATH/Statistics menu
mean(
list
[
, freqlist
]) ⇒
⇒⇒
⇒
expression
Returns the mean of the elements in
list
.
Each
freqlist
element counts the number of
consecutive occurrences of the corresponding
element in
list
.
mean({.2,0,1,ë.3,.4}) ¸ .26
mean({1,2,3},{3,2,1})
¸ 5/3
mean(
matrix1
[
, freqmatrix
]) ⇒
⇒⇒
⇒
matrix
Returns a row vector of the means of all the
columns in
matrix1.
Each
freqmatrix
element counts the number of
consecutive occurrences of the corresponding
element in
matrix1
.
In vector format rectangular mode:
mean([.2,0;
L1,3;.4,L.5]) ¸
[
L.133... .833...]
mean([1/5,0;
L1,3;2/5,L1/2]) ¸

list
) ⇒
⇒⇒
⇒
expression
Returns the median of the elements in
list1
.
median({.2,0,1,ë.3,.4}) ¸ .2
median(
matrix1
) ⇒
matrix
Returns a row vector containing the medians of
the columns in
matrix1
.
Note: All entries in the list or matrix must
simplify to numbers.
median([.2,0;1,ë.3;.4,ë.5]) ¸
