\bm{v}^{(m+1)} = R \bm{v}^{(m)} - B \bm{f}$$ We also saw that the convergence of the iterative calculation is dominated by the spectral radius $${ \rho(R) }$$ of the iteration matrix $${ R }$$. In ...

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 ...
