关于DFT调制多相综合滤波器组收发器的设计程序 （实部程序）(DFT modulated polyphase filter bank transceiver design program（real part）)

matlab程序设计入门举例.具有简单实用的优点。比较适合初学者进行有效的自学.(Introduction to Matlab programming example has a simple and practical advantages. Suitable for beginners to effective self-study.)

这是matlab的相关ppt，基本的一些操作和讲解，方便初学者更快的熟悉。(This is related to matlab ppt, and explain some of the basic operations, faster familiar easy for beginners.)

This is the thwaites method for boundary layer over flat plate . This is an empirical method based on the observation that most laminar boundary layers obey the following relationship .it will help our calculate coefficient drag , velocity over flat plate.

灰色系统理论是研究解决灰色系统分析、建模、 预测、决策和控制的理论.灰色预测是对灰色系统 所做的预测.目前常用的一些预测方法（如回归分 析等），需要较大的样本.若样本较小，常造成较 大误差，使预测目标失效.灰色预测模型所需建模 信息少，运算方便，建模精度高，在各种预测领 域都有着广泛的应用，是处理小样本预测问题的 有效工具(Grey system theory is the research and solution of grey system analysis, modeling, The theory of prediction, decision - making and control At present, some commonly used prediction methods (such as regression score) If the sample size is small, it often results in a comparison Large error, so that the prediction of the target failure Less information, convenient operation, high modeling accuracy, in a variety of prediction collar Fields are widely used to deal with small sample prediction problems Effective tool)

Matlab environment based on the independent component analysis (ICA) is the imagie mixed with the separation of simulation program (Matlab environment based on the independent component analysis (ICA) is the imagie mixed with the separation of simulation program)

用于计算rmse和r放的一个函数，只要输入预测值与实测值即可得到(A function used to calculate the rmse and R, just enter the predicted value and the measured values can be)

利用MALAB实现的关于变压器差流计算的问题，对差流的提取很有意义。(MALAB achieve on transformer differential current calculated differential current extraction makes sense.)
