LAPACK-3.4.1.tar
LAPACK,其名為Linear Algebra PACKage的縮寫,是一以Fortran程式語言寫就,用於數值計算的函式集。 LAPACK提供了豐富的工具函式,可用於諸如解多元線性方程式、線性系統方程組的最小平方解、計算特徵向量、用於計算矩陣QR分解的Householder轉換、以及奇異值分解等問題。(LAPACK (Linear Algebra PACKage) is a software library for numerical linear algebra. It provides routines for solving systems of linear equations and linear least squares, eigenvalue problems, and singular value decomposition. It also includes routines to implement the associated matrix factorizations such as LU, QR, Cholesky and Schur decomposition.)

:针对三容水箱是较为典型的非线性、时延对象,具有很强的代表性这一特点,
通过机理建模方法建立了三容水箱的一般数学模型。分析了线性和非线性阻力板的流量特性,
并通过实验测定了阻力板流量系数。最后给出了三容水箱的线性化模型。由仿真实验可知,非线性模型的阶跃响应和实验测得的响应曲线相吻合,(: For three-tank water tank is a more typical non-linear, time-delay object, has a strong representation of this characteristic, through the mechanism of modeling methods allow the establishment of three general mathematical model of water tanks. Analysis of linear and nonlinear flow resistance characteristics of plate, and through experimental determination of the resistance plate flow coefficient. Finally, the three-linear model of water tanks. By simulation experiments, we can see that the nonlinear model of step response and the experimentally measured response curve coincide)
