用模拟退火算法实现的车辆配送货问题，当时的智能算法作业，自己纯手编。希望对大家有用。

这是 一个程序来计算值的任何表达式 （使用堆栈） e.g. 3 * 5 + 2 * 4 - 5. 有效利用堆栈的太执行给定的任务 使用只有堆栈 immplementation 算法

! 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.

Newton差商插值，可输入数组进行插值运算-Newton difference quotient interpolation, may import array interpolation Operational

开源的的smt求解器，用于求解约束集的可满足性，能够支持位向量的求解，速度还算不错。

用于实现多相滤波结构，提高效率，通常用在实现通道划分的结构，通带平坦度更好，相对于其他的滤波器组结构来说有更优秀的通带和阻带性能

应用背景matlab仿真硬件时用的定点化仿真,一般用matlab 直接生成的滤波器响应仿真，因为结果是浮点的，所以和真实硬件计算出的结果差别很大。所以应当进行定点化处理，再检查响应曲线，在硬件设计（FPGA）就应该提前清楚到底要多和位的精度。关键技术输入参数是归一化的浮点数以及位宽，bit_floor.m用来仿真低位直接截断后的效果。bit_round.m是硬件按真正的四舍五入截断处理后的效果。bit_round_hw.m是仿真硬件处理里简化版四舍五入。
