迭代改进是威尔金森（Wilkinson）引入的一种技术，用于减少同时线性方程解过程中产生的圆误差。计算残差需要更高的精度算术。더더>>

这是有关有限的傅立叶变换的三个帖子系列中的第二个。这篇文章是关于快速FFT算法本身的。递归鸿沟和征服算法在一个名为FFTTX...더더>>

我们每天都使用傅里叶分析,甚至没有knowing it. Cell phones, disc drives, DVDs, and JPEGs all involve fast finite Fourier transforms. This post, which describes touch-tone telephone dialing, is the first of three posts about the computation and interpretation of FFTs. The posts are adapted from chapter 8 of my book,使用MATLAB的数值计算。...더더>>

Complex step differentiation is a technique that employs complex arithmetic to obtain the numerical value of the first derivative of a real valued analytic function of a real variable, avoiding the loss of precision inherent in traditional finite differences....더더>>

The Lambert W function deserves to be better known. It pops up in all sorts of places. And our MATLAB function for evaluating the function is a beautiful use of the Halley method....더더>>
