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. )

Compute resonances of a one-dimensional potential obtained by taking a spline with value VV(i) at each point xx(i). The behavior at the end points is chosen according to the "not-a-knot" condition if the end values are zero, the resulting (compactly supported) spline will be C^1 at the end points.
