说明：  对四进制调相方法进行了matlab仿真，经过验证，程序完整，可直接调用！(Quaternary phase modulation on matlab simulation methods, proven, program integrity, and can be called directly!)

This is one of the methods for face recognition using FLD method

使用matlab编写的经纬高、东北天数据和地心坐标数据之间的转换函数文件，包含了东北天坐标系的定义说明文件以及相关的转换公式。 三个函数的调用文件名：ECEFtoENV，ECEFtoLBH，LBHtoECEF。使用说明见函数的说明。(Prepared using matlab high latitude and longitude, northeast-day data and geocentric coordinate conversion functions between data file that contains the definition of the coordinate system Northeast day documentation and related conversion formulas. Three function calls filename: ECEFtoENV, ECEFtoLBH, LBHtoECEF. See the instructions for use function.)

It s the toolbox of multifractal in matlab .There is a help document in the rar .It s very helpful.

一些经典的传统标定文献，挺全的，还有用matlab做的Tasi标定中的共面法和异面法进行的标定精度分析程序(Some of the classic literature of traditional calibration, quite complete, there are to do with matlab Tasi coplanar calibration method and in-plane method of calibration accuracy of analytical procedures)

最小二乘法（又称最小平方法）是一种数学优化技术。它通过最小化误差的平方和寻找数据的最佳函数匹配。利用最小二乘法可以简便地求得未知的数据，并使得这些求得的数据与实际数据之间误差的平方和为最小。最小二乘法还可用于曲线拟合。其他一些优化问题也可通过最小化能量或最大化熵用最小二乘法来表达。 (Least-squares method (also known as least squares) is a mathematical optimization techniques. It does this by minimizing the square error of the data and find the best match function. The least square method can easily obtain the unknown data, and makes these data and the actual data obtained between the square and the smallest error. Least-squares curve fitting method can also be used. Other optimization problems can be maximized by minimizing the energy or entropy of the least square method to express. )
