crptrsR Documentation

Pointing to the columns of the component matrices.

Description

Given ICORE, i.e. the pointer to an element in CORE(p,q,r), this subroutine calculates the IA, IB and IC, pointing to the columns of the component matrices A, B and C that are responsible for the value in CORE(ICORE).

Usage

crptrs(icore, p, q, r)

Arguments

icore

The pointer to the core elements whose sign should be reversed.

p

The dimension number of the first mode.

q

The dimension number of the second mode.

r

The dimension number of the third mode.

Value

IA

The pointer to the columns of the first component matrix, given the pointer to an element in core.

IB

The pointer to the columns of the second component matrix, given the pointer to an element in core.

IC

The pointer to the columns of the third component matrix, given the pointer to an element in core.
