F01VAF (DTRTTP) copies a real triangular matrix, stored in a full format array, to a standard packed format array.
F01VAF (DTRTTP) packs a real
, stored conventionally in a full format array, into an array of length
. The matrix is packed by columns. 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.
Packed storage format is described in Section 3.3.2
in the F07 Chapter Introduction.
This example reads in a triangular matrix and copies it to packed format.
