! 2 ! HOMPACK90 is a suite of FORTRAN 90 subroutines for solving nonlinear 3 ! systems of equations by homotopy methods. There are subroutines for 4 ! fixed point, zero finding, and general homotopy curve tracking problems, 5 ! utilizing both dense and sparse Jacobian matrices, and implementing 6 ! three different algorithms: ODE-based, normal flow, and augmented 7 ! Jacobian. The (driver) subroutines called by the user are given in the 8 ! table below, and are well documented internally. The user need not 9 ! be concerned with any other subroutines in HOMPACK90. -! 2 ! HOMPACK90 is a suite of FORTRAN 90 subroutines for solving nonlinear 3 ! systems of equations by homotopy methods.

有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？  程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去掉不满足条件的排列。 

这个程序我用了两个月编写，功能已经和完整了，真是个好东西！好用着呢-this process I have spent two months of preparation, functions and integrity, is a good thing! Handy ability in

一些比较经典的数学问题源程序 包括百鸡百钱，灯塔问题，桃子猴问题-some of the more classic source of mathematical problems, including 100 hundred chickens money, Lighthouse, peach monkey issue

标准C写的数据直线拟合，最小二乘法处理，自己写的-write C standard linear data fitting, least squares method, wrote it myself
