fir滤波器，一个三频率信号的低通和带通滤波器(fir filter, a three-frequency signal of low pass and band-pass filter)

奥村（okumaura）模型模拟matlab代码(Okumura model simulation matlab code)

在matlab或者PSCAD中对桥差不平衡电流进行仿真计算，得到仿真结果与常规计算结果一致，此方法修改简单快捷。(In matlab or PSCAD to bridge the difference between the current imbalance in the simulation calculation, the simulation results are consistent with conventional calculations, this method is simple and quick modification.)

这是有关正弦波频率估计的几种算法，包括过零点检测，rife算法，music算法，levensen法，周期图法等7种不同算法。(This is several algorithm for frequency estimation of sinusoid, including zero crossing detection, rife algorithm, music algorithm, levensen method, periodogram method 7 different algorithms.)

Function that calculate the PSNR and WSNR of two imagines

matrix laboratory的缩写，矩阵实验室的意思。一开始它是一种专门用于矩阵数值计算的软件。自MATLAB4.0版本问世以来，该软件成为最具有吸引力，应用最为广泛的科学计算语言。我们这个课就拿MATLAB6.1版本来讲。（6.x版本大同小异） (At present, the MATLAB software is not only into the businesses, companies and research institutions, but also in institutions of higher learning from college students to doctoral students must master a basic skill is essential computational tools,)

MIMO Capacity and channel measurment

MATLAB下DLA二维程序源代码，可以模拟出二维图形并计算分形维数等(MATLAB under the DLA the 2D program source code, you can simulate two-dimensional graphics and calculation of the fractal dimension)

这个程序可以画出一个给定圆心和半径的圆，参数分别是x，y，r。(This program can draw a circle and the radius of a given circle, parameters are respectively the x, y, r)

matlab调用c程序经典实例,详细注释了接口函数和参数的意义功能，并以实例的形式完成matlab对c程序的调用(a classic example of matlab calling C source codes)
