说明：  小波阈值去噪的基本思想是先设置一个临界阈值λ，若小波系数小于λ，认为该系数主要由噪声引起，去除这部分系数;若小波系数大于λ，则认为此系数主要是由信号引起，保留这部分系数，然后对处理后的小波系数进行小波逆变换得到去噪后的信号。(The basic idea of wavelet threshold denoising is to set a threshold value of lambda first. If the wavelet coefficient is less than lambda, it is considered that the coefficient is mainly caused by noise and this part of the coefficient is removed. If the wavelet coefficient is larger than lambda, it is considered that the coefficient is mainly caused by signal, and this part of the coefficient is retained. Then the denoised signal is obtained by inverse wavelet transform of the processed wavelet coefficient.)

精通matlab6.5版_数值计算本章将花较大的篇幅讨论若干常见数值计算问题：线性分析、一元和多元函数分析、微积分、数据分析、以及常微分方程（初值和边值问题）求解等。但与一般数值计算教科书不同，本章的讨论重点是：如何利用现有的世界顶级数值计算资源 MATLAB。至于数学描述，本章将遵循“最低限度自封闭”的原则处理，以最简明的方式阐述理论数学、数值数学和 MATLAB计算指令之间的内在联系及区别。(matlab simulation)
