Description It is frequently necessary to manipulate large sparse matrices, for example in electrical network problems. In such cases much time and memory space can be saved if only the nonzero elements are stored. A set of Fortran subroutines has been written for performing various operations on sparse matrices stored in compact form in core. Core storage requirement is reduced for any square matrix less than 66 percent dense. These subroutines have been tested on an ZBM 360/50 using a "WATFOR… CONTINUE READING
