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
Background information to multithreading can be found in the Multithreading
This example reads in a triangular matrix and copies it to packed format.
