有限差分法 微分方程和积分微分方程数值解的方法。基本思想是把连续的定解区域用有限个离散点构成的网格来代替， 这些离散点称作网格的节点；把连续定解区域上的连续变量的函数用在网格上定义的离散变量函数来近似；把原方程和定解条件中的微商用差商来近似， 积分用积分和来近似，于是原微分方程和定解条件就近似地代之以代数方程组，即有限差分方程组 ， 解此方程组就可以得到原问题在离散点上的近似解。然后再利用插值方法便可以从离散解得到定解问题在整个区域上的近似解。 (Finite Difference Method Numerical solution of differential equations and integro-differential equation approach. The basic idea is to set a continuous solution of the region with a finite number of discrete points instead of a grid consisting of, these discrete points called grid nodes the solution of a continuous area on a given function of continuous variables used in the definition of discrete grid variable function approximation the original equation and boundary conditions in the micro-business operators to approximate differential, integral with the points and to approximate, so the original differential equations and boundary conditions are replaced by algebraic equations near Side, that is, finite difference equations , solve this equation group can get the original problem in discrete points on the approximate solution. And then using interpolation methods can be determined from the discrete solution of the problem solution of the approximate solution on the entire region)

matlab的模式识别工具箱，非常有助于开发(matlab tool of pattern recognition)

基于matlab的数字计算资料，既有程序也有案例，最新最全。(This book is a survey of the numerical methods that are common to undergraduate courses in Science, Computing, Engineering and Technology. The aim is to present sufficient methods to facilitate the numerical analysis of mathematical models likely to be encountered in practice. Examples of such models include the linear equations describing the stress on girders, bridges and other civil engineering structures, the differential equations of chemical and thermal reactions, and the inferences to be drawn from observed data.)
