matlab code and document for least square problem

These codes are about beamforming. receiver is like disc or ula.describtions are in m_files

大楼图像可以通用的几何畸变校正程序代码，不错。(The building images can be common geometric distortion correction code, yes.)

D = DISTMAT(X,Y) for matrices X and Y returns the distance matrix where the (i,j)th entry is the d-norm distance between the ith and jth row of X and Y respectively.

对matlab有很好的学习帮助，是很好的matlab经典教材。(On a good learning matlab help matlab is a very good classic textbook.)

重力异常的向上延拓程序，很实用，，推荐地球物理学生学习可直接使用。 (Gravity anomaly upward extension program, it is practical, and recommended geophysics student learning can be used directly.)

求不规则波导的散射参数的matlab程序，使用的matlab的微分工具箱（有限元法），总的来说还不错，附带实验报告。(Scattering parameters of irregular waveguides matlab program, using a differential matlab toolbox (finite element method), on the whole pretty good, with a test report.)

关于粗糙集计算的一些程序，使用matlab编写的，比较初级的(Calculated on the rough set some of the procedures, the use of matlab written relatively early)
