matlab nrs程序，含泪共享，需要的下载吧(matlab nrs procedures, sharing tears, need to download it)

说明：  现代数字信号处理的自适应滤波器设计程序，有详细备注(Modern digital signal processing, adaptive filter design process, contains a detailed Remarks)

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. )
