nPr(
Matrix1
,
Matrix2
)
⇒
matrix
Returns a matrix of permutations based on the corresponding
element pairs in the two matrices. The arguments must be the same
size matrix.
npv()
Catalog >
npv(
InterestRate
,
CFO
,
CFList
[,
CFFreq
]
)
Financial function that calculates net present value; the sum of the
present values for the cash inflows and outflows. A positive result for
npv indicates a profitable investment.
InterestRate
is the rate by which to discount the cash flows (the cost
of money) over one period.
CF0
is the initial cash flow at time 0; it must be a real number.
CFList
is a list of cash flow amounts after the initial cash flow
CF0
.
CFFreq
is a list in which each element specifies the frequency of
occurrence for a grouped (consecutive) cash flow amount, which is
the corresponding element of
CFList
. The default is 1; if you enter
values, they must be positive integers < 10,000.
nSolve()

upBound
⇒
number or error_string
Iteratively searches for one approximate real numeric solution to
Equation
for its one variable. Specify the variable as:
variable
– or –
variable
=
real number
For example, x is valid and so is x=3.
Note:
If there are multiple solutions, you can use a guess to
help find a particular solution.
nSolve()
attempts to determine either one point where the residual
is zero or two relatively close points where the residual has opposite
signs and the magnitude of the residual is not excessive. If it cannot
achieve this using a modest number of sample points, it returns the
string “no solution found.”
