Indefinite matrices collected by Nick Gould, Yifan Hu, and Jennifer Scott.
The GHS_indef and GHS_psdef collection includes matrices from the Matrix
Market (math.nist.gov/MatrixMarket), Rutherford-Boeing collection (Duff,
Grimes, and Lewis), the Parasol project (see below), Kumfert and Pothen,
CUTE/CUTEr optimization test set, the UF sparse matrix collection
(those are excluded here), Andy Wathen, Mario Arioli, Christian Damhaug,
Alison Ramage, Anshul Gupta (Gupta's matrices are in the UF collection
under the Gupta directory), Olaf Schenk (matrices from Olaf Schenk are
located here, as well as in the existing Schenk_* directories),
Miroslav Tuma, Maros and Meszaros, and the Dept. of Mathematical
Modelling in DIAMO (Czech Republic).
See ftp://ftp.numerical.rl.ac.uk/pub/matrices/symmetric/ for the
GHS collection.
NOTE: matrices can have upper-case or lower case matrix-type fields
(rsa or RSA, for example).
