Polynomial argmin approximation of functions

Here is a Matlab prototype of the algorithm described in D. Henrion, M. Korda, J. B. Lasserre. Polynomial argmin for recovery and approximation of multivariate discontinuous functions, HAL 03986252, February 2023.

  • Source file polyargmin.m for Matlab - requires the interface YALMIP as well as a semidefinite solver e.g. MOSEK.

    And here are the illustrative examples:

  • test1dpolyargmin.m for univariate functions
  • test2dpolyargmin.m for bivariate functions
