指纹识别技术的matlab源程序。可以基于这些代码进行二次开发。在matlab中，设置当前的目录为工作目录，在命令行中输入fpextractdemo，即可运行程序。(Matlab source fingerprint recognition technology. Can be based on the code for secondary development. In matlab, set the current directory as working directory, the command line, enter fpextractdemo, you can run the program.)

最速下降法又称为梯度法，是1847 年由著名数学家Cauchy 给出的，它是解析法中最古老的一种，其他解析方法或是它的变形，或是受它的启发而得到的，因此它是最优化方法的基础。这里给出其Matlab源程序。(The steepest descent method, also known as gradient method, was in 1847 given by the famous mathematician Cauchy, it is the oldest analytical method one, other analytical method or its variants, or inspired by it obtained and therefore it is the basis for the optimization method. Here are its Matlab source.)
