F01VCF (DTPTTR) unpacks a real triangular matrix, stored in packed format in a one-dimensional array, to full format in a two-dimensional array.
Packed storage format is described in Section 3.3.2
in the F07 Chapter Introduction.
F01VCF (DTPTTR) unpacks a real
, stored in a one-dimensional array of length
to conventional storage in a two-dimensional array. This routine is intended for possible use in conjunction with routines from Chapters F06
where some routines use triangular matrices stored in the packed form.
This example reads in a triangular matrix packed by columns and unpacks it to full format.
