Second, compared with direct tensor product in multi-dimensional space, which suffers from the exponential increase of the number of sampling points with the number of variables, the Sparse Grid technique decreases the number of collocation points dramatically while the accuracy is guaranteed, and further reduces the computational complexity.

其次，为了避免通常用于多维空间的直接张量积随机配置法所带来的采点数随空间维度指数增长的缺点，采用稀疏网格采点技术，在保证建模精度的同时大幅度减少了配置点数目，从而进一步降低了随机配置法的计算复杂度。

Analysis of dynamic instability of interfacial slip waves based on the surface impedance tensor.

Because Matlab uses complex matrix as its basic unit, we provided the matrix form of the Bezier curve and tensor product Bezier surface, and presented the ways to achieve them by using Matlab. On such a basis, we obtained the algorithm, made feasible programs and demonstrated them by concrete examples. Such a study aims at promoting the realization of CAGD toolbox by using Matlab.

由于Matlab的基本编程单元是复数矩阵，因此首先归纳出了一维Bezier曲线和二维张量积型Bezier曲面的矩阵表示形式，在此基础上形成算法，编写了可实现的程序，随后以具体实例的形式给予验证，最终得到了满足要求的曲线和曲面，以期能够推动Matlab的CAGD专业工具箱的产生。
