Positive definite matrices from Christian Damhaug, DNV Software. Originally collected by Nick Gould, Yifan Hu, & Jennifer Scott, some in unassembled finite-element form (and some in both forms). (Note: these matrices were previously in the GHS_psdef directory). NOTE: matrices can have upper-case or lower case matrix-type fields (rsa or RSA, for example). -------------------------------------------------------------------------------- ==> Fcondp2.readme <==
