恩，就是三次样条插值，小弟刚刚学会编程，大家见谅，见谅...

一个流体数值模拟程序，模拟空中或从一个钻孔运动中筛选不饱和区。三维空气流动的异常，各向异性饱和带空气流通。-A fluid numerical simulation program to simulate the air or from a drilling campaign in the filter is not saturated zone. The abnormal three-dimensional air flow, anisotropy saturated with air circulation.

应用背景Massive multiuser MIMO (MISO): ◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50) ◮ coherent, but simple, processing ◮ Potential to dramatically improve rate & reliability ◮ Potential to drastically scale down TX power ◮ Not only theory, at least one known testbed (64× ∼10) 关键技术 Massive MIMO Operation Not enough resources for pilots & CSI feedback, so operate in TDD. ◮ On the uplink, ◮ acquire CSI from uplink pilots and/or blindly from data ◮ detect symbols ◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal ◮ On the downlink, ◮ use CSI obtained on the uplink ◮ make necessary adjustments based on reciprocity calibration ◮ apply multiuser MIMO precoding ◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ... ◮ MRC/MRT operation ◮ intracell interference will appear as

这是五个经典的c语言源程序-This is the classic five source language c

应用背景 该算法主要应用于人脸识别，通过利用特征脸和PCA来实现的。 关键技术运用主成分分析（PCA）对图像进行降维，利用特征脸来提取人脸特征，并且根据最近邻法对待识别人脸进行判定。其中调用了OpenCV中的函数。

此程序能将模拟滤波器转变为数字滤波器,在数字信号处理问题上有着广泛的应用-analog filter into digital filters, in digital signal processing problem has wide application
