ssmooth: Semi-smooth approximation

In randall-romero/CompEconR: An R version of Miranda & Fackler's CompEcon toolbox for MATLAB

Description

Computes \tilde f(x) = φ^-(φ^+(f(x),a-x),b-x) and its derivative

Usage

ssmooth(x, a, b, fx, J)

Arguments

x	n-array of evaluation points
a	n-array of lower bounds
b	n-array of upper bounds
fx	n-array of function f evaluated at f
J	n.n matrix of Jacobian of f (optional)

Value

If input J is provided, it returns a list with fields

• f n.1 matrix, function evaluated at x

• J n.n matrix, Jacobian evaluated at x

Otherwise, it returns only the matrix f.
