你好，


有没有人有一个很好的链接到一些代码来计算C中函数的渐变

？


谢谢，

谷歌知道所有。我敢打赌C中的数字食谱也可能是一个安全的开始赌注，但目前还不方便。

C中的一个函数？


Google知道所有。我敢打赌C中的数字食谱也可能是一个安全的开始赌注，但目前还不方便。

好​​吧，据我所知，C中的Numerical Recipes要求你自己编写

命令（dfunc？）。此外，谷歌搜索似乎没有产生任何

即时答案。


这应该是一个常见的任务，我打赌那里的一些C用户有

分享一些不错的代码？任何人;）


谢谢，

Hello,

Does anyone have a nice link to some code for calculating the gradient
of a function in C?

Thanks,

Google knows all. I bet "Numerical Recipes in C" might also be a safe
bet for a start, but it is not handy at the moment.

Well, as far as I can see Numerical Recipes in C asks you to write the
command yourself (dfunc?). Also, googling does not seem to yield any
immediate answers.

This should be such a common task, that I bet some C users out there has
some nice code to share? Anyone ;)

Thanks,
