Description: LAPACK是用Fortran90和规定套路解决系统同步线性方程组，最小二乘解线性方程组，特征值问题，以及奇异值问题。相关的矩阵分解（陆，乔莱斯基，快速反应，分解，舒尔，广义Schur ）也提供了，因为有关的计算，如重新安排的舒尔分解和估计条件号码。致密带状矩阵的处理，而不是一般稀疏矩阵。在所有领域，类似的功能是提供真正的和复杂的矩阵，在单，双精度-LAPACK is written in Fortran90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision

Description: 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.

Description: 对结构响应信号进行连续复Morlet小波变换，根据小波系数的模极大值提取小波脊线，识别结构的瞬时频率；为降低噪音的影响，采用奇异值分解(SVD)方法进行降噪处理，建立了一种基于连续复小波变换识别时变系统
瞬时频率的方法。用一个具有时变刚度的弹簧质量系统的数值算例验证方法的有效性，随后设计了一个时变拉索
结构试验，分别对索施加线性和正弦变化的拉力，同时测试结构的冲击响应，运用提出的方法成功地识别了索的瞬时频率。数值与试验结果表明，提出的方法能有效地识别时变结构的瞬时频率，且识别方法具有一定的抗噪性。-On the structural response signal continuously Complex Morlet wavelet transform, the wavelet coefficients extracted wavelet modulus maxima ridge line, identify the structure of the instantaneous frequency to reduce the effects of noise, using singular value decomposition (SVD) method for noise reduction, the establishment of A complex wavelet transform based on continuous time-varying systems instantaneous frequency identification method. With a time-varying stiffness spring-mass system numerical example effectiveness of the method, followed by the design of a time-varying cable structural testing, respectively Suoshi Jia linear and sinusoidal variation of tension, while the impulse response of the test structure, the use of the proposed method successfully identified the cable instantaneous frequency. Numerical and experimental results show that the proposed method can effectively identify the structure of time-varying instantaneous frequency, and the identification method has some n
