Specify coefficient matrix type of sparse linear equations DSLEMA
Name DSLEMA
Specify coefficient matrix type of sparse linear equations
Purpose This subprogram specifies whether the coefficient matrix is symmetric, or
unsymmetric but with symmetric structure. A call to DSLEMA is optional for
symmetric case. For the unsymmetric case, DSLEMA must be called
immediately after DSLEIN.
NOTE Matrix structure input by matrix supports five data types. Matrix structure
input by elements, columns, and finite elements supports only REAL*8
precision.
