matlab - 如何在 MATLAB 的 for 循环中调用函数？

Question

我想像这样在循环中调用(执行)一个 m 文件(函数):

global m, r
m = 2;
for n = 2:10;
  for r1 = 0:n-m;
    r2 = n-m-r1;
    r = [r1,r2];   
    [Call the function here?????????]
  end
end

这是函数:

function main
  x0 = [-0.5403,0.5471];
  fsolve(@fcn,x0)

function z = fcn(X)
  rand('twister',5409);
  global m, r
  a = rand(m,1);
  for i = 1:m
    sm(i) = 0.0;
    for l = m-i+1:m
      sm(i) = sm(i)+r(l);
    end
    s = 1.0/(i+sm(i));
    g(i) = (a(i))^s;     
  end
  prod = 1.0;
  for k = 1:m
    prod = prod * g(m+1-k);
    u(k) = 1.0-prod;
    x(k) = (sqrt(3)/pi)*log(u(k)/(1-u(k)));
  end
  sum = 0;
  sum1 = 0;
  sum2 = 0;
  for j = 1:m
    sum = sum+(r(j)+2)*(1/(1+exp((-pi/sqrt(3))*((x(j)-X(1))/X(2)))));
    sum1 = sum1+(r(j)+2)*((x(j)-X(1))/X(2))*(1/(1+exp((-pi/sqrt(3))*((x(j)-X(1))/X(2)))));
    sum2 = sum2+(x(j)-X(1))/X(2);
  end
  z(1) = pi/(X(2)*sqrt(3))*(-m+sum);
  z(2) =(-1/X(2))*(m+(pi/sqrt(3))*(sum2-sum1));

非常感谢您的帮助。

函数main 和fcn 应该保存在名为“main.m”的文件中。您必须确保此文件位于您当前的工作目录或 somewhere on the MATLAB path (如 Amro 的评论中所述)，以便 MATLAB 可以使用它。由于 main 不需要输入参数也没有输出参数，因此您可以通过以下任何一种方式调用它:

main
main;
main()
main();
