介绍matlab7中各种实例的电子图书，比较不错，对初学者有较大帮助。(Description matlab7 various examples of e-books, relatively good, greater help for beginners.)

以mathematica9中文版来计算由牛顿迭代法产生的实根。因开发环境中没有mathematica,故只好选matlab.(Using mathematica9 to calculate the real root produced by the Newton iterative method. The station is estimated without.)

任意比例缩小图象，支持JPG和24为真彩色位图。初学者小看一下……(Any scaled-down images, support for JPG and 24 for true color bitmap. Beginners to belittle you ... ...)

无循环实现S变换，S变换在信号分析中十分有效，它的时空分辨率要高于小波变换，效率很高的程序(This code computes the Stockwell transform (S-Transform) of a one dimensional series without for loop, thereby making it computationally fast and simple. S-Transform was proposed in 1996. A nice tutorial on S-Transform can be found here: djj.ee.ntu.edu.tw/S_Transform.pdf‎ )
