i always wonder if the matrix is inverted through implicit method such as ICCG instead of explicit LU deposition, will the round off error still produce +ve off diagonal C elements. chris -----Original Message----- From: Ray Anderson [mailto:Raymond.Anderson@xxxxxxx] Sent: Friday, August 31, 2001 3:43 PM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Re: non-negative off diagonal capacitive matrix elements ?? Thanks to all who responded on my question of non-negative off diagonal elements in a capacitance matrix. As I thought, the concensus opinion was that the very small positive number was down in the numerical noise and is essentially a zero entry in the matrix. Thanks again. -Ray ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
