mat4list() MATH/List menu
mat4list(matrix) ⇒ list
Returns a list filled with the elements in
matrix. The elements are copied from matrix
row by row.
mat4list([1,2,3]) ¸{1 2 3}
[1,2,3;4,5,6]!M1 ¸
[
1
2 3
4 5 6]
mat4list(M1) ¸{1 2 3 4 5 6}
max() MATH/List menu
max(expression1, expression2) ⇒ expression
max(list1, list2) ⇒ list
max(matrix1, matrix2) ⇒ 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},{ë4,3}) ¸{1 3}
max(list) ⇒ expression
Returns the maximum element in list.
max({0,1,ë7,1.3,.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,ë3,7;ë4,0,.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])
¸
[ë2/15 5/6]
mean([1,2;3,4;5,6],[5,3;4,1;
6,2]) ¸[47/15, 11/3]
median() MATH/Statistics menu
median(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])
¸
[.4 ë.3]
