利用一组简单的数据，来说明直接反演的不适定性，及利用菲利普斯光滑化方法求解-Using a simple set of data to illustrate the direct inversion of ill-posed, and the use of smoothing method for solving Phillips

主要是对空间离散的三维数据【x,y,z】点进行连接,这个方法可以使曲线更加的光滑连续，无plot3函数产生线条的生硬。 -Mainly discrete three-dimensional data space {x, y, z] point connection, this method can make more smooth and continuous curve, without plot3 function generates blunt lines.
