The netlib ( http://www.netlib.org ) has several excelent tested FORTRAN and C functions written by approved numeric experts. More over, the usage of netlib functions is free, searching for "sparse matrix" gives 20 pages of software tools. There is no need to buy the NR software. Efficiently implement any of the standard sparse matrix solvers in the top level Mathematica language seems allmost impossible due to the lack of pointers. Regards Jens
