What is Hermite interpolation used for?

Hermite interpolation. In numerical analysis, Hermite interpolation, named after Charles Hermite, is a method of interpolating data points as a polynomial function. The generated Hermite interpolating polynomial is closely related to the Newton polynomial, in that both are derived from the calculation of divided differences.

What is Makima cubic Hermite interpolation in MATLAB?

In MATLAB, 'makima' cubic Hermite interpolation addresses requirements (1) and (2) outlined above. To eliminate overshoot and avoid edge cases of both numerator and denominator being equal to 0, we modify Akima's derivative formula by tweaking the weights w 1 and w 2 of the slopes ? i ? 1 and ? i:

What is the difference between Lagrange and Hermitian interpolation?

Lagrange interpolation is a special case of Hermite interpolation. In Lagrange interpolation, you obtain shape functions by fitting a curve for the field variables of a problem without concerning its derivatives. Generate the simplest Hermitian interpolation function, , that is linear, one-dimensional, and has only two nodal points.

How do you find the Hermite polynomial?
