| Abstract: | On the basis of algebraic equations of discretized solution-determination problem of partial differential equations in bounded plane domain,a new interpolation method-numeri- cal diferential interpolation(NDI) is described- Using unknown function's values on arbitrari-ly distributed points in bounded plane domain,NDI can be used to calcucate values on any points in the domain. It is also suitable for bounded domains in 1-dimension or higher di-mension space,and has wide backgrounds of applications. |
