## Group IBM_EDA

Group Description |
Circuit simulation matrices from Tim Lehner, IBM EDA. Added March, 2006. The dc* matrices are DC operating point problems, and the trans* matrices are transient simluations. All come from the same circuit. As in most circuit matrices, these matrices are permutable into block triangular form, and the also have a few dense rows/columns (normally from voltage and current sources).
