cr.sparse.opt.build_grad_val_func¶
- cr.sparse.opt.build_grad_val_func(func, grad)[source]¶
Constructs a grad_val function from the definitions of function \(f(x)\) and gradient \(g(x)\)
- Parameters
func – Definition of the smooth function \(f : \RR^n \to \RR\)
grad – Definition of the gradient \(g = \nabla f : \RR^n \to \RR^n\)
- Returns
A function which computes the pair \((g(x), f(x))\) for input \(x\)
