nfMin()
Catalog >
nfMin(
Expr
,
Var
)
⇒
value
nfMin(
Expr
,
Var
,
lowBound
)
⇒
value
nfMin(
Expr
,
Var
,
lowBound
,
upBound
)
⇒
value
nfMin(
Expr, Var
) |
lowBound
<
Var
<
upBound
⇒
value
Returns a candidate numerical value of variable
Var
where the local
minimum of
Expr
occurs.
If you supply
lowBound
and
upBound
, the function looks between
those values for the local minimum.
nInt()
Catalog >
nInt(
Expr1, Var, Lower, Upper
)
⇒
expression
If the integrand
Expr1
contains no variable other than
Var
, and if
Lower
and
Upper
are constants, positive
ˆ
, or negative
ˆ
, then
nInt()
returns an approximation of
‰
(
Expr1
,
Var
,
Lower
,
Upper
)
.
This approximation is a weighted average of some sample values of
the integrand in the interval
Lower
<
Var
<
Upper
.
The goal is six significant digits. The adaptive algorithm terminates
when it seems likely that the goal has been achieved, or when it
seems unlikely that additional samples will yield a worthwhile
improvement.
A warning is displayed (“Questionable accuracy”) when it seems that
the goal has not been achieved.
Nest
nInt()
to do multiple numeric integration. Integration limits can
depend on integration variables outside them.
nom()
Catalog >
nom(
effectiveRate,CpY
)
⇒
value
Financial function that converts the annual effective interest rate
effectiveRate
to a nominal rate, given
CpY
as the number of
compounding periods per year.
effectiveRate
must be a real number, and
CpY
must be a real number
> 0.
Note:
See also
eff()
, page 32.
norm()
Catalog >
norm(
Matrix
)
⇒
expression
norm(
Vector
)
⇒
expression
Returns the Frobenius norm.
