说明：  结构振动反应。在强烈地震波德作用下，2个自由度相对位移和绝对加速度的反应，考虑了阻尼的影响。(struture response due to ground motion.during a big ground motion,one 2 degree of freedom-structure s relative displacement and absolute acceleration response.consider damping raion.)

一种多目标优化算法的matlab程序，能够实现大量目标的同时优化，对多目标优化算法的学习很有帮助(a multi-object optimization matlab program,can optimize large object at meantime it will contribute to those who want to study muti-object optimization algorithm)

Chebfun is an open-source software system for numerical computing with functions. The mathematical basis is piecewise polynomial interpolation implemented with what we call “Chebyshev technology”. The foundations are described, with Chebfun examples, in the book Approximation Theory and Approximation Practice (L. N. Trefethen, SIAM 2013). Chebfun has extensive capabilities for dealing with linear and nonlinear differential and integral operators, and also includes continuous analogues of linear algebra notions like QR and singular value decomposition. The Chebfun2 extension works with functions of two variables defined on a rectangle in the x-y plane.
