silabs公司的si1010芯片的接收电平指示，即RSSI(silabs company si1010 chip reception level indication,)

可轻松实现短时傅里叶变换及对应逆变换，可更改程序内部窗函数，自行选择合适窗函数进行分析(Short-time Fourier transform and corresponding inverse transform can be easily realized. The internal window function of the program can be changed and the suitable window function can be selected by oneself for analysis.)

数值分析中 二分法查找带GUI图形界面的源码(Numerical analysis of binary searching with the source code of the GUI graphical interface)

灰色模型算法，通过改进之后，考虑了之后的误差处理，减少了因为数据变化太大而引起的预测不准确的现象。(Gray model algorithm, improvements, after taking into account the error handling, reduced because the data has changed so much caused by inaccurate forecasts phenomenon.)

本书介绍了matlab在控制系统中的使用，涉及matlab的基本操作及系统的频谱分析、状态空间分析等内容(This book describes the matlab use in the control system, the content spectrum analysis involves matlab basic operations and systems, state space analysis, etc.)

模态处理相关程序，包括时域，频率，自普，互普，相干，频响，时频分析，HHt，随机减量法等等，很不错，可以借鉴(Modal treatment-related procedures, including time domain, frequency, since the S & P, each P, coherence, frequency response, time-frequency analysis, HHt, random decrement method, etc., very good, can learn)

说明：  都是关于空间普估计算法，其中有解相干和非相干算法以及它们之间的对比( the spatial spectrum estimation)
