Follow-up Comment #3, bug #55263 (project octave): I further tested the case with 2D data and 1D data with discontinuities. In the 1D case the Nelder-Mead method performs very well, regardless of discontinuities. This supports the point of view that the 2D and higher implementation has some incorrect indexing somewhere, where it is decided along which dimension to perform the contracting and the shrinking portion of the algorithm. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?55263> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
