说明：  有关信号与信息系统的matlab程序--傅立叶级数和变换(Signal and information systems related to the matlab procedure- Fourier series and transform)

This MATLAB Code plot BER Vs Eb/No for M_ary PSK with different values of M. The user can choose the desired BER and the code will tell what is the required Eb/No to achieve this BER for different values of M. In addition, a plot for shannon limit is available.

利用卫星观测文件和导航文件进行单点定位，德国导航文件官网提供，程序很精炼(Using satellite observation files and navigation files for single point positioning)

simple clustering using imperialist competitive algorithm

COUNTERDELETE(NAME) removes the counter specified by name permanently

对锅炉现场数据辨识后，分别采用GPC和DMC进行控制，采用m文件进行编程。(The boiler field data identification, respectively GPC and DMC control, use the m file programming.)

根据已给数据，画出风场示意图。有图例，方向。(draw wind field)

这是一些MATLAB图形用户设计界面的源程序，对初学着有帮助哦！(which is a MATLAB graphical user interface design of the source of a novice to help!)
