进行边角网的平差，输入测量数据即可平差计算出待定点的坐标(Corner of the net adjustment, input measurement data to the adjustment calculation to be determined coordinates of the point)

说明：  Rosenbrock函数 评价函数，可用于优化算法测试，在原点处取到全局最小值(Rosenbrock function The evaluation function can be used to test the optimization algorithm, and the global minimum value of 0 is taken at the origi)

说明：  这是一个最基础的php程序，适合新手练习学习之用(This is the most basic PHP program)

统计学习是计算机及其应用领域的一门重要的学科本书全面系统地介绍了统计学习的主要方法，特别是监督学习方法，包括感知机、K近邻法、朴素贝叶斯法、决策树、逻辑斯谛回归、与最大熵模型、支持向量机、提升方法、EM算法、隐马尔可夫模型和条件随机场等。(Statistical learning is an important subject in the field of computer and application of this book comprehensively systematically introduces the main methods of statistical learning, especially the supervision method of study, including the perception, K neighbor method, naive bayesian method, decision tree, logistic regression, and the maximum entropy model, support vector machine (SVM), promotion methods, the EM algorithm, the hidden markov model and conditional random field, etc.)

说明：  本次实验是基于广泛测试的公开加密库来实现数字签名服务。这里选择了 M2Crypto 加密库来实现，M2Crypto 加密库能够完整的支持 OpenSSL 库，所以会 更加方便点。而且这个库中包含有 RSA 非对称加密算法（M2Crypto.RSA），高级 的加密解密接口（M2Crypto.EVP）,还能操作 X.509 证书(M2Crypto.X509)。我们 可以先通过 M2Crypto 库里的模块来生成证书、公钥文件和私钥文件，后面再利 用生成的证书、私钥和公钥来实现加密解密及数字签名认证。(This experiment is based on a widely tested public encryption library to implement digital signature services. Here is the choice The M2Crypto encryption library is implemented, and the M2Crypto encryption library can fully support the OpenSSL library, so it will It's more convenient. And this library contains a RSA asymmetric encryption algorithm (M2Crypto.RSA), high level The encryption and decryption interface (M2Crypto.EVP) can also operate the X.509 Certificate (M2Crypto.X509). We A certificate, a public key file, and a private key file can be generated by the modules of the M2Crypto repository first, and the later will be beneficial. The encrypted decryption and digital signature authentication are realized with the generated certificate, private key and public key.)
