发帖数: 44 | 1 Hello:
any one know how to obtain the derivative of the cubic spline interpolation
results using a program ?
I am thinking about using a program to find the cubic spline interpolation
and the
derivative of the cubic spline interpolation results based on the input. the
example input file is listed below: a list of potential energies of a pair
particles as a function of the distance
r1 E1
r2 E2
r3 E3
r4 E4
r5 E5
The goal is to find the interpolated potential and force (negative
derivative of the c | B****g

spline coefficients, then you can compute gradient
interpolation
