DERIVATIVE-CALCULATION-
利用Matlab内建的快速傅氏变换函数可以方便地在波数域计算重磁异常导数。介绍了基于Matlab语言的波数域求导的算法，给出了程序源代码，讨论了一些有助于提高计算精度的编程技巧。通过模型试验和数据分析，
发现在计算垂向导数时波数域求导算法的精度比傅氏级数的精度有明显改善；而水平导数的计算，2种方法的精度相当。在某区钾盐勘探中，用该方法处理高精度重力剖面数据，取得了较好效果。(It is convenient to calculate derivative in wave number space using the inbuih F胛function in Matlab．This paper describes
a matlab algorithm for derivative calculation of 1 D gravity and magnetic anomaly in wave number space，gives code of program and
deals with some programming skills for precision improvement．Throngh model test and data analysis，it is found that the precision of
the F盯method is much higher than that of the Fourier Series method in vertical derivative calculation．In horizontal derivative calculation，
however，the precisions of the two methods ale almost the same．During kainite exploration in a certain basin，satisfactory result
Wag obtained in the processing of gravity profile data using this method．)

BFGS
拟牛顿法和最速下降法(Steepest Descent Methods)一样只要求每一步迭代时知道目标函数的梯度。通过测量梯度的变化，构造一个目标函数的模型使之足以产生超线性收敛性。这类方法大大优于最速下降法，尤其对于困难的问题。另外，因为拟牛顿法不需要二阶导数的信息，所以有时比牛顿法(Newton s Method)更为有效。如今，优化软件中包含了大量的拟牛顿算法用来解决无约束，约束，和大规模的优化问题。(The quasi-Newton method and the Steepest Descent Methods only require that each step iterations know the gradient of the objective function. By measuring the change of the gradient, constructing a model of the objective function is sufficient to produce superlinear convergence. This method is much better than the steepest descent method, especially for difficult problems. In addition, because the quasi-Newton method does not require information on the second derivative, it is sometimes more effective than the Newton s Method. Today, the optimization software contains a large number of quasi-Newton algorithm used to solve the unconstrained, constraint, and large-scale optimization problems.)
