varSamp( ) varSamp(List[, freqList]) ⇒ expression Returns the sample variance of List. Each freqList element counts the number of consecutive occurrences of the corresponding element in List. Note: List must contain at least two elements. If an element in either list is empty (void), that element is ignored, and the corresponding element in the other list is also ignored. For more information on empty elements, see page 131. varSamp(Matrix1[, freqMatrix]) ⇒ matrix Returns a row vector containing the sample variance of each column in Matrix1. Each freqMatrix element counts the number of consecutive occurrences of the corresponding element in Matrix1. If an element in either matrix is empty (void), that element is ignored, and the corresponding element in the other matrix is also ignored. For more information on empty elements, see page 131. Note: Matrix1 must contain at least two rows. W Catalog > warnCodes( ) Catalog > warnCodes(Expr1, StatusVar) ⇒ expression Evaluates expression Expr1, returns the result, and stores the codes of any generated warnings in the StatusVar list variable. If no warnings are generated, this function assigns StatusVar an empty list. Expr1 can be any valid TI-Nspire™ or TI-Nspire™ CAS math expression. You cannot use a command or assignment as Expr1. StatusVar must be a valid variable name. £ ¡ ¢ To see the entire result, press and then use and to move the cursor. For a list of warning codes and associated messages, see page 143. when( ) when(Condition, trueResult [, falseResult][, unknownResult]) ⇒ expression Returns trueResult, falseResult, or unknownResult, depending on whether Condition is true, false, or unknown. Returns the input if there are too few arguments to specify the appropriate result. Omit both falseResult and unknownResult to make an expression defined only in the region where Condition is true. Use an undef falseResult to define an expression that graphs only on an interval. when() is helpful for defining recursive functions. Catalog > 110 TI-Nspire™ Reference Guide

varSamp()
Catalog >
varSamp(
List
[
,
freqList
]
)
⇒
expression
Returns the sample variance of
List
.
Each
freqList
element counts the number of consecutive occurrences
of the corresponding element in
List
.
Note:
List
must contain at least two elements.
If an element in either list is empty (void), that element is ignored,
and the corresponding element in the other list is also ignored. For
more information on empty elements, see page 131.
varSamp(
Matrix1
[
,
freqMatrix
]
)
⇒
matrix
Returns a row vector containing the sample variance of each column
in
Matrix1
.
Each
freqMatrix
element counts the number of consecutive
occurrences of the corresponding element in
Matrix1
.
If an element in either matrix is empty (void), that element is ignored,
and the corresponding element in the other matrix is also ignored. For
more information on empty elements, see page 131.
Note:
Matrix1
must contain at least two rows.
warnCodes()
Catalog >
warnCodes(
Expr1
,
StatusVar
)
⇒
expression
Evaluates expression
Expr1
, returns the result, and stores the codes
of any generated warnings in the
StatusVar
list variable. If no
warnings are generated, this function assigns
StatusVar
an empty
list.
Expr1
can be any valid TI-Nspire™ or TI-Nspire™ CAS math
expression. You cannot use a command or assignment as
Expr1
.
StatusVar
must be a valid variable name.
For a list of warning codes and associated messages, see page 143.

when()
Catalog >
when(
Condition
,
trueResult
[
,
falseResult
][
,
unknownResult
]
)
⇒
expression
Returns
trueResult
,
falseResult
, or
unknownResult
, depending on
whether
Condition
is true, false, or unknown. Returns the input if
there are too few arguments to specify the appropriate result.
Omit both
falseResult
and
unknownResult
to make an expression
defined only in the region where
Condition
is true.
Use an
undef
falseResult
to define an expression that graphs only
on an interval.
when()
is helpful for defining recursive functions.
