Initialize sparse linear equations DSLEIN
Name DSLEIN
Initialize sparse linear equations
Purpose This subprogram provides the necessary information to begin processing with
the sparse linear equation solution package. For a nonsymmetric matrix (LU
factorization), this call must be followed by a call to DSLEMA.
NOTE Matrix structure input by matrix supports five data types. Matrix structure
input by elements, columns, and finite elements supports only REAL*8
precision.
Usage VECLIB:
INTEGER*4 neqns, msglvl, output, ier
REAL*8 global(150)
CALL SSLEIN(neqns, msglvl, output, global, ier)
