在MATLAB中,fsolve函数用于求解非线性方程组。当你看到输出信息“fsolve completed because the vector of function values is near zero”时,这意味着fsolve已经成功找到了一个解,使得函数值向量接近于零。下面是对这一消息的详细解释和建议: fsolve函数的作用: fsolve是MATLAB中的一个函数,用于求解非线性方程组。其...
Let's say I have a vector of known values: A = [10;20;30;100;200;10;20;30;40;50]; I'm looking for a way to get MATLAB to automatically create vector B of unique values, based on A. So for the 7 unique values in A, B = [1;2...

我猜你的代码应该是 surf(Xp(i),Yp(i),Zp(i)) 出错了吧，当x和y为1*10的向量时，则构成了一个10*10的二维平面，因此此时z应该是一个10*10的矩阵，而不是标量或矢量，错误提示：Z must be a matrix, not a scalar or vector
matlab错误:FUN should return a column vector of the same length as Y我用Matlab估计一两个参数, 函数式为: hq = ( ln2 - ln(a^q+b^q) ) / (q*ln2); 代码如下 function beta = fitHq(q, hq, beta0) % function beta = fitHq(q, hq, beta0); % fun = inline('(log(2) - (log...
