cr.sparse.opt.smooth_build3

cr.sparse.opt.smooth_build3(func, grad, grad_val)

Creates a a smooth function with user defined grad and grad_val functions

Parameters

• func – Definition of the smooth function $f:{\mathbb{R}}^n\to \mathbb{R}$

• grad – Definition of the gradient $g=\mathrm{\nabla }f:{\mathbb{R}}^n\to {\mathbb{R}}^n$

• grad_val – Definition of a combined function which computes the pair $(g(x),f(x))$

Returns

A smooth function wrapper

Return type

SmoothFunction
