Calculates the median-median line and updates all
the system statistics variables.
All the lists must have equal dimensions except for
list5 .
list1 represents xlist.
list2 represents ylist.
list3 represents frequency.
list4 represents category codes.
list5 represents category include list.
Note:
list1 through list4 must be a variable name or
c1–c99 (columns in the last data variable shown in
the Data/Matrix Editor).
list5 does not have to be a
variable name and cannot be c1–c99.
In function graphing mode:
{0,1,2,3,4,5,6}! L1 ¸ {0 1 2 ... }
{0,2,3,4,3,4,6}! L2 ¸ {0 2 3 ... }

mid() MATH/String menu
mid( sourceString , start [, count ]) ⇒ string
Returns count characters from character string
sourceString , beginning with character number start .
If
count is omitted or is greater than the dimension of
sourceString , returns all characters from sourceString ,
beginning with character number
start .
count must be ‚ 0. If count = 0, returns an empty
string.
mid("Hello there",2) ¸
"ello there"
mid("Hello there",7,3)
¸
"the"
mid("Hello there",1,5)
¸
"Hello"
mid("Hello there",1,0) ¸
""
mid( sourceList , start [, count ]) ⇒ list
Returns count elements from sourceList , beginning
with element number
start .
If
count is omitted or is greater than the dimension of
sourceList , returns all elements from sourceList ,
beginning with element number
start .
count must be ‚ 0. If count = 0, returns an empty list.
mid({9,8,7,6},3) ¸ {7 6}
mid({9,8,7,6},2,2)
¸ {8 7}
mid({9,8,7,6},1,2)
¸ {9 8}
mid({9,8,7,6},1,0)
¸ {}
mid( sourceStringList , start [, count ]) ⇒ list
Returns count strings from the list of strings
sourceStringList , beginning with element number
start .
mid({"A","B","C","D"},2,2) ¸
{"B" "C"}
min() MATH/List menu
min( expression1 , expression2 ) ⇒ expression
min( list1, list2 ) ⇒ list
min( matrix1, matrix2 ) ⇒ matrix
Returns the minimum of the two arguments. If the
arguments are two lists or matrices, returns a list or
matrix containing the minimum value of each pair of
corresponding elements.
min(2.3,1.4) ¸ 1.4
min({1,2},{ë 4,3})
¸ {ë 4 2}
