    光学设计软件zemax源码: This DLL models an nular aspheric surface as described in: "Annular surfaces in annular field systems" By Jose M. Sasian Opt. eng. 36 (12) P 3401-3401 December 1997 This surface is essentially an odd aspheric surface with an offset in the aspheric terms. The sag is given by: Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ... Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.

    crc任意位生成多项式 任意位运算 自适应算法 循环冗余校验码(CRC,Cyclic Redundancy Code)是采用多项式的 编码方式,这种方法把要发送的数据看成是一个多项式的系数 ,数据为bn-1bn-2…b1b0 (其中为0或1),则其对应的多项式为: bn-1Xn-1+bn-2Xn-2+…+b1X+b0 例如:数据“10010101”可以写为多项式 X7+X4+X2+1。 循环冗余校验CRC 循环冗余校验方法的原理如下: (1) 设要发送的数据对应的多项式为P(x)。 (2) 发送方和接收方约定一个生成多项式G(x),设该生成多项式 的最高次幂为r。 (3) 在数据块的末尾添加r个0,则其相对应的多项式为M(x)=XrP(x) 。(左移r位) (4) 用M(x)除以G(x),获得商Q(x)和余式R(x),则 M(x)=Q(x) ×G(x)+R(x)。 (5) 令T(x)=M(x)+R(x),采用模2运算,T(x)所对应的数据是在原数 据块的末尾加上余式所对应的数据得到的。 (6) 发送T(x)所对应的数据。 (7) 设接收端接收到的数据对应的多项式为T’(x),将T’(x)除以G(x) ,若余式为0,则认为没有错误,否则认为有错。

    This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr

    Implemented BFS, DFS and A* To compile this project, use the following command: g++ -o search main.cpp Then you can run it: ./search The input is loaded from a input file in.txt Here is the format of the input file: The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm. The second line of input file shoud be an integer m indicate the number of connections for the map. Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist. The following input are for A* The following line contains two chars indicate the source and destination city for A* algorithm. Then there is an integer h indicate the number of heuristic. The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.
