摘要
将有限差分和有限元两种近似方法用统一的公式表示,使不同近似格式有了一个统一形式.
This paper deals with approximate methods which give finite element and finite difference a universal treatment. Consider the equation
Lu = 0,(x,y) ∈Ω. u = u0,(x,y) ∈αΩ . The general approximate form of (L) is
which is decided by FS , Rlos(O) and v(x,y). The approximate solution and its precision are decided uniquely by the error estimation E in FS.
