一本关于利用Matlab进行有限元分析的书籍。是Kattan的第二版。多是关于单元类型的分析。(A book about finite element analysisusing Matlab. Second edition of Kattan. Mainly about element type analysis.)

软开关在开关电源中的重要地位不言而喻，此代码实现了电源的软开关控制(Soft switching in the switching power supply in an important position is self-evident, this code implements the soft-switching power supply control)

CC1020芯片的中文技术资料,对于用CC1020做信号的朋友相信会有帮助(CC1020 chip s Chinese technical information, I believe it will be helpful for the friends to develop projects about signal by CC1020)

fir滤波器，7、8、13、14，对信号进行alpha、betagamma滤波，调用方法 Hd = fir_alpha 滤波后信号 = filter(Hd,原信号) 得到的信号是时域信号，plot直接显示(Fir filter, 7, 8, 13, 14, alpha filter for signal method is called Hd = fir_alpha After filtering signal = filter (Hd, the original signal) Signal is time domain signals, the plot showed directly)

利用LFSR生成伪随机序列（m序列） 对待隐藏的图像进行加密然后利用线性插值的方法隐藏于载体图像中。 代码很完整 用的是MATLAB7.0(Use LFSR to generate pseudo-random sequence (m sequence) to treat encryption to hide the image and then use linear interpolation method of hidden images in the vector. Complete code is used in MATLAB7.0)

上海交大硕士毕业论文《基于最小熵谱估计的 高频重建算法研究》：本论文提出了一种基于最小熵谱估计的高频重建算法（论文中简称为（MEHFR），该算法利用最小熵准则对信号谱进行外推，从而重建出音频信号的高频分量，论文同时对提出的MEHFR算法作了改进和性能分析，并给出了MEHFR成功应用于目前主流音频编解码器——MP3的一个实例(This thesis puts forward an algorithm of high frequency reconstruction based on minimum entropy spectral estimation (called MEHFR in this thesis). MEHFR spreads the spectrum in the principle of minimum entropy and reconstructs the high frequency of audio signals also this thesis improves MEHFR and shows the analyses of performance at last applies MEHFR to ME3 which is the most popular codec of audio.)
