Description: 一、 Seidel迭代法
算法8.2:
1. 输入矩阵A,右端项b ,初始迭代向量 X(0) ,维数n,容许误差ε ,最大容许迭代次数 N。
2. 置k=1.
3. 计算
X1=(b1-Σa1jxj(0))/a11 j=2,3,…….,n
Xi=(bi-Σaijxj-Σaijxj(0))/aii, i=2,3,……,n-1
Xn=(bn-Σanjxj)/ann j=1,2,…….,n-1
4.若||X-X(0)|| <ε,输出X , 停机;否则,转步骤5。
5.若k<N,k+1=>k,X=>X(0),转步骤3;否则输出失败信息,停机

Description: 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。-crc-generating polynomial arbitrary Operators adaptive algorithm Cyclic Redundancy Check (CRC. Cyclic Redundancy Code) is the polynomial coder, This way the data to be sent as a polynomial coefficient data bn - 1bn-2 ... b1b0 (0 or 1), corresponding to the polynomial : bn - 1Xn-1 bn - 2Xn-2 ... b1X belts such as : data "10010101" polynomial can be written as a X7 X4 X2. Cyclic Redundancy Check Cyclic Redundancy Check method of principle as follows : (1) The data to be sent to the corresponding polynomial p (x). (2) the sender and the receiver agreed on a generator polynomial G (x), set up the generator polynomial of the highest power of r. (3) In the data block Add to the end of r-0, then the polynomial corresponding to M (x) = XrP (x). (R-bits) (4) M (x) divided by G (
