L-BFGS 算法_matlab该函数完成上述的 L-BFGS 算法,利用双循环算法计算下降方向,并利用线搜索确定步长。初始化和迭代准备函数输入: x 为迭代的初始点, fun 提供函数值和梯度, opts 为提供算法参数的结构体。函数输出: x 为迭代得到的解, f 和 g 为该点处的函数值和梯度, Out 为记录迭代信息的结构体。
L-BFGS-B is a fantastic NNLS solver, and much better than Matlab's lsqnonneg. Links: The fortran lbfgsb is at http://users.eecs.northwestern.edu/~nocedal/lbfgsb.html, There are also versions 2.1 and 2.4 of the library. For v 2.1, Peter Carbonetto's mex interface works; see http:...

I've designed an interface to the L-BFGS-B solver so that it can be called like any other function in MATLAB. 인용 양식 Peter Carbonetto (2025). MATLAB interface for L-BFGS-B (https://www.mathworks.com/matlabcentral/fileexchange/15061-matlab-interface-for-l-bfgs-b), MATLAB ...
A pure Matlab implementation of the L-BFGS-B algorithm. Introduction The L-BFGS-B algorithm is a limited memory quasi-Newton, gradient based optimzation algorithm to solve problems of the form: minimize f(x) such that l <= x <= u Motivation The L-BFGS-B algorithm uses a limited memor...

Matlab在R中是否与等价? 我意识到lsqcurvefit在Matlab中是可用的,但我特别想要一个使用基于导数的方法的函数,理想情况下,它与nlminb使用的方法完全相同。对于受约束的问题,我不想使用由'trust-region-refelective'改进的lsqcurvefit方法。 浏览1提问于2013-11-21得票数 0 ...
