如何在MATLAB中调用for循环中的函数？

Question

我想在循环中调用(执行)一个m文件(函数),如下所示:

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

这是功能:

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.

功能main和fcn应保存在一个名为"main.m文件"的文件.您必须确保此文件位于当前工作目录中或MATLAB路径上的某个位置(如Amro的注释中所述),以便MATLAB可以访问它.由于main不需要输入参数且没有输出参数,因此您可以通过以下任何一种方式调用它:

main
main;
main()
main();
