Interpolation with prescribed values of derivatives instead of function values. (English). Aplikace matematiky, vol. 16 (1971), issue 6, pp. 421-430
MSC: 65-04, 65D05 | MR 0292261 | Zbl 0224.65002 | DOI: 10.21136/AM.1971.103377
Summary:
The following interpolation problem is considered: There are given points and at some of them the functional values are prescribed. At the other points only the values of the derivatives are given. Some conditions for existence and uniqueness are formulated and the problem is reduced to the problem of solving a system of linear equations for the unknown function values. An algorithm for finding the matrix and the right hand side of this system is suggested which uses an interpolation method for finding the derivatives of the given interpolation polynomial.
