matlab：fmincon，将变量传递给nonlcon [英] matlab: fmincon, pass variables into nonlcon

问题描述

我知道它是一个愚蠢的问题，但我不知道如何解决它......让我说我有这样的事情：

  x = fmincon（@ myfun，x0，A，b，Aeq，beq，lb，ub，@ mycon）
  

以及后来的：

 函数[c，ceq] = mycon（x）
c = ... 
 ceq = ... 
  

如何将附加变量传递到 $ mycon ，例如

 函数[c，ceq] = mycon（x，变量）
如果变量== 1 
c = ... 
 ceq = ... 
 else 
c = ... 
 ceq = ... 
 end 
  

感谢：）

mycon 作为匿名函数传递：

   x = fmincon（@ myfun，x0，A，b，Aeq，beq，lb，ub，@（xx）mycon（xx，变量））
  

请注意，变量在 fmincon 行被调用。

I know its a stupid question, but I have no idea how to solve it... Lets say I have something like:

x = fmincon(@myfun,x0,A,b,Aeq,beq,lb,ub,@mycon)

and later on :

function [c,ceq] = mycon(x)
c = ...     
ceq = ...   

How to pass additional variables into @mycon, such as

function [c,ceq] = mycon(x, variable)
if variable == 1 
    c = ...     
    ceq = ... 
else   
    c = ...     
    ceq = ... 
end

Thanks :)

解决方案

You pass mycon as anonymous function:

   x = fmincon(@myfun,x0,A,b,Aeq,beq,lb,ub,@(xx)mycon(xx,variable))

Note that variable is fixed at the moment the fmincon line is called.
