nfMin()
Catalog
>
nfMin(Expr, Va r) ⇒ value
nfMin(Expr, Va r, lowBound) ⇒ value
nfMin(Expr, Va r, lowBound, upBound) ⇒ value
nfMin(Expr, Var) | lowBound<Va r<upBound ⇒ value
Returns a candidate numerical value of variable Va r 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 Va r, and if
Lower and Upper are constants, positive ˆ, or negative ˆ, then
nInt() returns an approximation of ‰(Expr1, Va r , Lower, Upper).
This approximation is a weighted average of some sample values of
the integrand in the interval Lower<Va r <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(Ve c to r ) ⇒ expression
Returns the Frobenius norm.
