A new paper ‘A deterministic gradient-based approach to avoid saddle points’ by Lisa Maria … WebLet say I have a function F[x_,y_]:=x^2+6y^ (3/2) Now I want to plot a 2D plot of F [ ] vs x, and need to use y variable as a color gradient. Here I want to vary y as a color axis and the values of F will be plotted against x it will be like this but with different function Reply Flag 39 Replies Sort By: Replies Likes Recent 0

WebIn this article, a new numerical gradient scheme based on the collocation polynomial and Hermite interpolation is presented. The convergence order of this kind of method is also O ( τ 2 + h 4 ) under the discrete maximum norm when the spatial step size is twice the one of H-OCD, which accelerates the computational process. ...
