编写程序将含有20个数据的数组M分成两个数组：正数组P和负数组N，并分别统计两个数组的个数，显示在屏幕上。(Write a program containing the data array 20 is divided into two arrays M: positive and negative groups Array P N, and the number of two arrays statistics were displayed on the screen.)

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．)

由于自校正控制器在实际中的广泛运用，其缺点日益明显，主要体现在变阶次、变时延和变参数的系统中，因此研制具有较强的鲁棒性的控制器在实际运用中非常有用。Clark等人提出的广义预测控制自校正控制器是一种基于参数模型的预测控制算法，它采用了时段优化性能指标，结合辨识和自校正机制，从而克服自校正控制中存在的缺点，具有较强的鲁棒性。(self-tuning controller in practice the widespread use of its increasingly obvious shortcomings, mainly reflected in the change of Order, Variable Delay and change parameters in the system, developed with the robustness of the controller in actual application is very useful. Clark and others put the GPC self-tuning controller is based on the parameters of a model predictive control algorithm, it uses time optimize performance indicators, combining literacy and self-correction mechanism, in order to overcome self-tuning control of the shortcomings, with strong robust.)
