E. Navarro et al., A MATRIX APPROACH TO THE ANALYTIC-NUMERICAL SOLUTION OF MIXED PARTIAL-DIFFERENTIAL SYSTEMS, Computers & mathematics with applications, 30(1), 1995, pp. 99-109
In this paper, analytic-numerical solutions for initial-boundary Value
problems related to systems of partial differential equations, are pr
oposed. Given an admissible error epsilon > 0 and a finite domain G, a
numerical approximation is constructed in terms of the data, so that
the error is uniformly upper bounded by epsilon in G.
