InterpolatingPolynomial

Usage

• InterpolatingPolynomial[data, var] gives a polynomial in the variable var which provides an exact fit to a list of data.
• The data can have the forms {{, }, {, }, ... } or {, , ... }, where in the second case, the are taken to have values 1, 2, ... .
• The can be replaced by {, , , ... }, specifying derivatives at the points .

Notes

• With a list of data of length , InterpolatingPolynomial gives a polynomial of degree .

• Example: InterpolatingPolynomial[4, 5, 8, x].
