Hi, the question of supporting RFP (*) has come up a couple of times on this forum, the answer being that there is no current plan for it. Has the situation changed? The application I have in mind is symmetric rank-k update (LAPACK xsfrk).

(*) RFP is a storage format for triangular, symmetric and hermitian matrices which only stores the upper triangle but in a clever way so as to allow writing algorithms rich in BLAS level 3 operations. http://www.netlib.org/lapack/lawnspdf/lawn199.pdf
