于慧敏版信号与系统第二版部分自己编的部分matlab程序代码... (YU Hui-min version of the second edition of part of the signal and system part of their series of matlab code ...)

分别使用LS和TLS算法，计算出混合信号的频率。该频率估计算法的数学模型是基于ARMA模型。其中还包括详细的设计报告，有一定的参考价值。(LS and TLS algorithms were used to calculate the mixed-signal frequency. The mathematical model of the frequency estimation algorithm is based on ARMA models. It also includes detailed design report, a certain reference value.)

该源码是针对一篇避免过度分割提出的一种新的分水岭算法，具体matlab源码，针对各个步骤都给出了具体分析，个人觉得对学习图像分割的有帮助。(The source is to avoid over-segmentation for a proposed a new watershed algorithm matlab source code specific for each step are given a specific analysis, personal feel to learn image segmentation help.)

cosmic下载数据，读取其中的有用数据，phs，prof等数据，画出电离层电子密度(cosmic download data, read one of the useful data, phs, prof other data, draw the ionospheric electron density)

说明：  用函数从样本图像中形成投影，然后用这些投影重构图像(With the function formed from the sample image projection, and then use these projections of the reconstructed image)

谱估计 (1)修正协方差法 (2)多重信号分类（MUSIC）算法 (3)ESPRIT算法 (4)皮萨论科（Pisarenko）谐波分解法 并对各算法进行分析。 解压后即可在MATLAB上运行(spectral estimation (1) the amendment of covariance (2) multiple signal classification (MUSIC) algorithm (3) ESP RIT algorithm (4) On order pizza's from Branch (Pisarenko) harmonic decomposition of each algorithm for analysis. Unpacked can run in MATLAB)

蝙蝠算法（BatAlgorithm，缩写BA），是一种元启发式优化算法，是杨新社（音译自：Xin-SheYang）在2010年提出的算法。这个蝙蝠算法以微蝙蝠（microbats）回声定位行为的基础，采用不同的脉冲发射率和响度。(Bat algorithm (BA), a meta-heuristic optimization algorithm, was proposed by Xin-SheYang in 2010. Based on the echolocation behavior of microbats, this bat algorithm uses different pulse emissivity and loudness.)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )
