1This port builds the module CSparse of SuiteSparse. 2 3CSparse is a Concise Sparse Matrix package. This code goes with the book "Direct 4Methods for Sparse Linear Systems," Timothy A. Davis, SIAM, Philadelphia, 2006. 5 6Note: the CSparse library is meant for personal experimentation. For system-wide 7installation, please install math/suitesparse-cxsparse instead. 8
