WebI am using fminsearch to fit parameters for a system of DEs to observed data. I am not expecting to get a great fit. fminsearch pretty quickly finds what appears to be an acceptable min for the objective function, but then does not stop. It's running for a really long time, and I cannot figure out why. I am using the options Webfminunc和fminsearch都是MATLAB中用于求解无约束优化问题的函数，但它们有一些区别。 fminunc是使用牛顿法或拟牛顿法求解优化问题的函数，它需要提供目标函数的梯度信息。因此，当目标函数的梯度容易计算时，fminunc是一个很好的选择。 fminsearch是使用单纯 …
