hello all sorry for the following "none" R related question. does anyone know of a reference to calculate the following identity: |I + ABC| where I is an identity matrix and A, B,C may not have to be square matrices? you help will be greatly appreciated. H. V. Henderson; S. R. Searle SIAM Review, Vol. 23, No. 1. (Jan., 1981), pp. 53-60. provides a result to calculate the inverse of I + ABC. (for those interested!!!) thanking you in advance Allan Clark ======== Lecturer in Statistical Sciences Department University of Cape Town 7701 Rondebosch South Africa TEL (Office): +27-21-650-3228 FAX: +27-21-650-4773 http://web.uct.ac.za/depts/stats/aclark.htm
