题主给出的错误警告的意思是，提供的目标函数评估失败。FMINCON无法继续。目标函数评估失败的原因是，由于la、d、b、Cb、b1、t等变量没有赋值，所以在执行目标函数时，不能得到一个具体的数值。解决的方法，可以在主程序和目标函数中，使用全局变量来声明la、d、b、Cb、b1、t等变量，即 global la d...
fmincon是用于求解非线性多元函数最小值的matlab函数。由于用户应用的目标函数出现以下错误，FMINCON函数无法继续执行
Hello im trying to minimise a function of two variable, where the parameter P, h and E are given, and im getting the error "Failure in initial objective function evaluation. FMINCON cannot continue.". the fmincon and function codes are shown below, any help would be appreciated...
FMINCON cannot continue. I was thinking that the problem may be that I only have to pass the initial value m0 to the fmincon function instead of, as I did now, the vector ThemeCopy Y0=[y0;v0;h0;0;m0;w0;a0]; Firstly I get exact the same errors and second...
我们如下分析下fmincon(myfun...)中的myfun必须是目标函数的句柄或者对应M文件名字符串，记住只能是这两...

我们如下分析下fmincon(myfun...)中的myfun必须是目标函数的句柄或者对应M文件名字符串，记住只能是这两种！！！当你的目标函数是M文件时，那么我们可以如下调用句柄方式：fmincon(@myfun...)文件名方式：fmincon('myfun'...)，由于文件名可以作为M函数来调用当你的目标函数是子函数时，那么只能使用句柄...
