给定一个子波计算LS反滤波。有点小问题。你们帮忙看看...(Given a wavelet compute the LS inverse filter)

一种不同信噪比噪声的添加方法，包括复噪声和实噪声，()

说明：  产生水平地震波的小程序，希望对作地震分析的同仁有用处！(level of seismic waves generated by small program, and I hope to make seismic analysis of the usefulness of us!)

基于KT指数的船舶旋回运动仿真，可以在此基础上进行修改添加，方便大家(KT index based on ship motion simulation cycle can be modified on this basis, to add, to facilitate)

用于结构振动模态分析,可用于简单分析一些多自由度结构的频率等(Modal analysis for structural vibration can be used for simple analysis of the structure of a number of multi-frequency degrees of freedom)

奇异值分解用于英文文本检索，画出频率矩阵第一奇异值向量和第二奇异值向量的分布图( a fast retrieval algorithm for English texts is proposed. First of all, the English texts are mapped into frequency matrixes of order 26 and the dimensions of texts representation space are reduced through Singular Value Decomposition. Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. )

说明：  车牌定位，用MATLAB编写的代码，用于车牌号码的二值化等，便于车牌的识别。(License plate location, using MATLAB code written for the license plate numbers of two values and so easy to license plate recognition.)

内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

卡尔满滤波的matlab程序，可以用的，可以试一试，并修改一下(Carl full matlab filtering procedures can be used to try and make some corrections)

卡尔曼滤波的理解，利用一个简单的正弦信号来进行卡尔曼滤波，从而更好的理解卡尔曼滤波。(Understanding of the Kalman filter, with a simple sinusoidal signal to the Kalman filter so as to better understand the Kalman filter.)
