prodVA: Product of three dimentional array in vector.

In nlr: Nonlinear Regression Modelling using Robust Methods

Description

Array(n*p*p)*Vector(n*1) is (p*p) matrix equal the sum of vector multiple first dimention of array.

Usage

prodVA(ary, vector)

Arguments

ary	(n*p*P) numeric array.
vector	(p*p) matrix.

Details

It can be used to multiple a (n*p*p) Hessian into (n*1) vector of residuals.

Value

(p*p) matrix.

Note

It is used in optimization and loss functions, may not explicitly called by user. May be used in defining loss functions by user.
