在使用Matlab解决人口模型问题时,遇到一个常见的错误:“Not enough input arguments”。这是一个典型的非线性最小二乘拟合问题。为了更好地理解并解决这个问题,我们首先编写一个函数,用于定义人口增长模型。函数的具体内容如下:function f = nihe(x, xdata)f = x(1)./(1 + (8.523^(-1)*...
Not enough input arguments.没有足够的输入参数。问题出在,fmincon()格式不对。fun前少加一个@符号 应为 [x,fval,exitflag,output]=fmincon(@fun,x0,[],[],[],[],lb,ub,@mycon)注意在英文格式下输入
ChatGPT 是这么回答的: By moving theFUNCfunction outside of the script and using@FUNCas the input argument forode45, MATLAB will be able to recognize the function and parameters correctly, and the “Not enough input arguments” error should be resolved. 我恍然大悟,原来是没加 @ 符号!!!添加上...

fmincon stopped because it exceeded the function evaluation limit,options.MaxFunEvals = 200 (the default value).意思是:警告:信赖域反射算法不解决这类问题,利用有效集算法。你也可以尝试内点算法:设定算法选择内部点”并重新运行。在fmincon中的460行,求解器过早停止。fmincon停止因为它超过了功能...
这是一个叫做fun的函数,函数的输入为P1,输出为PP3,如果直接点击运行函数则会出现‘Not enough input arguments‘的错误,需要给P1传值才可以调用函数。方法一:在函数内部直接给P1赋值。P1=一个常数。方法二:在函数外部调用函数pp3=fun(常数)你...
I have the following function definition: ThemeCopy function output = y(x) output = exp(x)/(2 +(x^3)); end I am trying to pass an array through a function elementwise and generate an output array in which every item is simply the value the function for the respective input item. ...
