matlab编程完成一GPS网的平差计算。起算数据见文件“起算数据.TXT”；GPS网略图见“网图.jpg”；基线向量观测值和方差见“基线.bas”。根据已知起算数据和观测值建立数学模型并进行最小二乘平差计算和精度评定。代码和计算结果在实习报告中也已详细列出。(matlab program to complete a GPS network adjustment calculation. Initial data the document entitled " Initial Data. TXT" GPS network sketch map, see " Map. Jpg" baseline vector and the variance of observations, see the " baseline. Bas" . According to initial data and observations of known mathematical model and the least squares calculation and accuracy evaluation. Code and report the results in practice have also been detailed.)

【债券回购量化投资模型】：本人在投资公司做量化投资的，分享一个简单的债券回购量化投资模型，在rar压缩文件附有数据，模型的原理与策略系历史最大开盘价合约进场，细节不多讲，做量化投资的朋友可以了解一下。([Bond repurchase quantitative investment model]: I do quantitative investment in investment companies, sharing a simple bond repurchase quantitative investment model, rar compressed files with data, principles and strategy of the largest in the history of opening contract model approach , not much talk about the details, do the quantitative investment friends can look at.)

维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始(Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec)
