Domain decomposition methods constitute a fundamental strategy in numerical analysis, enabling the partitioning of large and complex computational problems into smaller, more manageable sub-problems.

Considering the linear systems $Ax = b$, where the matrix $A$ is irreducible and diagonally dominant, we obtain bounds for the spectral radius of the $L_{r,\omega ...

If the SINGLE option is not used, PROC MODEL computes values that simultaneously satisfy the model equations for the variables named in the SOLVE statement. PROC MODEL provides three iterative methods ...
