interpolate()

interpolate(xValue, xList, yList, yPrimeList)
This function does the following:
xList yList xList
Given , =f( ), and
unknown function f, a cubic interpolant is used to approximate the
xValue
function f at . It is assumed that
increasing or decreasing numbers, but this function may return a
value even when it is not. This function walks through
xList xList
for an interval [ [i],
an interval, it returns an interpolated value for f(
returns undef.
xList yList yPrimeList
, , and
contain expressions that simplify to numbers.
xValue
can be a number or a list of numbers.
