Objective function is undefined at initial point. Fmincon cannot continue. That message is ONLY given if the very first call to the function fails. The initial point would have been moved to fit in the ub lb if needed, and to fit the linear constraints...
针对你提出的问题“objective function is returning undefined values at initial point. lsqcurvefit cannot continue.”,这是在使用MATLAB的lsqcurvefit函数进行非线性最小二乘拟合时常见的错误。以下是针对此问题的详细解答,包含检查和修改目标函数的步骤: 检查目标函数在初始点是否正确定义: 确保目标函数能够处理所有输...

I tried running your code and along with the error messages mentoined by you I also encountered some other errors, one of which being Unrecognizedfunction or variable 'GEsolve'. This indicates that you have not defined the 'GEsolve' function. This function is ...
The error is in this sense self-explaining: You provide an initial guess to function 'lsqcurvefit', where the value of the objective function has undefined values. As a matter of fact, you can check that by evaluating the objective function yourself on the star...

2.2.2 用function对象WebScriptObject执行自己 由于在 JS 中,每个 funciton 其实都是对象,所以我们还可以直接取得 window.x 叫这个对象执行自己。 在JS 里头如果这样写: window.x.call(window.x, 1); Objective-C 中便是这样: WebScriptObject *x = [[webView windowScriptObject] valueForKey:@"x"]; ...
如果方法返回一个结构体,如果结构体是Mac OS X ABI Function Call Guide中定义的在寄存器中返回的,那么发送给nil的消息返回0,结构体中的每一个字段都为0。其他的结构体类型不会自动为0。 如果方法返回上述类型以外的类型,发送给nil的消息返回值为未定义(undefined)。
简单理解:“Runtime is everything between your each function call.” 但是大家要明白,第二点我提到runtime并不只是因为它带来了这些简便的语言特性。而是这些简单的语言特性,在实际运用中需要你从完全不同的角度考虑和解决问题。只是计算1+1,很多语言都是一样的,但是随着问题的复杂,项目的增长,静态语言和动态语言...
