parameters about components. To do so, I'm trying to optimize my functions to determine the unknown parameters and the system reliability. I'm using fmincon but I got an error. I know it musts return a scalar v
针对您遇到的 MATLAB 错误 "supplied objective function must return a scalar value",以下是一些解决步骤和建议: 检查目标函数是否返回标量值: 在MATLAB 中,优化函数(如 fmincon)期望目标函数返回一个单一的数值(标量),而不是向量、矩阵或其他复杂数据结构。因此,您需要确保您的目标函数最终只返回一个数值。 例如...

I am trying to do an optimization for a function using a "fmincon" function. I have got an error and couldn't find the problem. The following is the error obtained : ThemeCopy Error using fmincon (line 609) Supplied objective function must return a scalar value. Error in Topo_3D (line...
Supplied objective function must return a scalar value. To run the above matlab code, when K=1, i can have only one value i=1, then parameter values can be taken as follows. ThemeCopy A=3.5153e+21;eta = 1; H_DL = 1.0e+02 * [ 7.3460 + 2.3079i; 2.0984 - ...
