crptrs | R Documentation |
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).
crptrs(icore, p, q, r)
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. |
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. |
