M.m`在这里插入代码片function J = M(a,b,c,d,J,ite)% Explanation：% a : Z的实部虚部取值下界% b : Z的实部虚部取值上界% c : C的虚部% d : C的实部% J : Z的初始取值% ite: 迭代次数NN = a:0.001:b;[Re,Im] = meshgrid(N);Z = Re+Im*1i;C = c*sqrt(-1)-d;for n = 1:ite t = abs(Z)<=2; J = J

具体问题取自：https://wenku.baidu.com/view/530d58cbeef9aef8941ea76e58fafab068dc4456.html求解代码：clear all% 与图2对应的参数相匹配即可f = @(x)0.2*x(1)^2 + 0.2*x(2)^2 + 0.2*x(3)^2 + 310*x(1) + 305*x(2) + 300*x(3) - 1000 % 目标函数Aeq = [1,1,1];beq = 170;x0 = [60,0,0];A = [-1,0

Question:Matlab语言：fun.mfunction f = fun(x , y)f = y - 2 * x / yEuler1.mfunction y = Euler1(x0, xn, y0, n)x = x0;y = y0;%设置步长为h = 0.1h = 0.1;for i = 1: 1/h yp = y + h * fun(x,y); x = x0 + i * h; y = yp; fprintf('x%d = %f y%d

idea:来自好友的提问，枚举4个数字随机组合相加的所有结果，推广到多个，很遗憾我能力有限，只做成了4个的matlab代码，欢迎大佬指点或者有想法的朋友与我交流。code:clear all;clc;A = input('请输入格式如下的四个数字：[2,3,4,6]');A = sort(A);B = [];n = length(A);for circle = 2:n switch circle case 2 for i = 1:n

Bernstein多项式公式:Bernstein定理成立：若f在[0，1]上连续，则在[0，1]上Bn(f)一致收敛于f.一般地，若导数f(k∈N)在[0，1]上连续，则在[0，1]上Bn(f)的k阶导数一致收敛于f.若x0∈(0，1)是f的第一类间断点，则：function y=bb(x,n,i)y=nchoosek(n,i)*x.^(n-i).*(1-x).^(i);%nchoose...
