一次函数的迭代不动点我会求 也知道应用 我想问的是二次或二次以上函数的迭代不动点及应用 就拿下面这个题目讲解一下就可以 （……（（（x-2)^2-2)^2-……-2)^2 一共1981个括号 求x^2的系数 Matlab求迭代如何显示过程值如图.可以用matlab连续计算这样的迭代值么?不仅仅要最终结果.要具体具体具体的~再问下怎么画这些迭代值的变化曲线么?用来看他的收敛速度. jacobi迭代 matlab系数矩阵A=D-L-U,D=[2 0 0;0 3 0;0 0 2;]L=[0 0 0; 1 0 0; 0 1 0] U=[0 1 0; 0 0 1; 0 0 0],b=[1;8;-5]已经输入”x的初值x^(0)=[0;0;0]迭代过程x^(k+1)=inv（D)*(L+U)*x^(k) + inv(D)*b“这一过程如何在matlab中输入实 Matlab迭代这个程序有些错误,请大家帮我修改修改function Martin(a,b,c,N)f=@(x,y)(y-sign(x)*sqrt(abs(b*x-c)));g=@(x)(a-x);m=[0;0];for n=1:Nm(:,n+1)=[f(m(1,n),m(2,n),g(m(1,n)))];endplot(m(1,:),m(2,:),'kx');axis equal; matlab迭代问题－－50分用循环迭代求取c点的轨迹,和移动的g点轨迹假设xA为已知,先取xC1＝xA；k＝[sqrt（R0^2+(e^2-1)*xC1^2）]/xC1；此为c点的法线斜率,xC2＝xA-r/sqrt（1＋k^2）；zC2＝[R0－sqrt（R0^2+(e^2-1) 《山市》与《海市》的不同点? 是several thousand还是several thousands of ?RT这两种我都见过。。 一.单项选择.1.He left without _____ "Goodbye" to us.A.saying B.to say C.said Dsay2.How much didi it _____ you?A.spendB.payC.costD.take3.That's _____ expensive .Do you have a _____ one?A.too;cheapB.more;cheapC.too;cheaperD.much;cheaper.我辛辛 Several people were robbed in the dark and narrow(窄的)streets of our town in a week.
