相控阵雷达资源调度的详细说明及了解，其中包含了多篇代表性的文献。(A detailed description and understanding of the phased array radar resource scheduling, which includes a representative literature.)

rayleigh信道仿真，一种简单的实现方法，具有一定的参考价值(Rayleigh channel simulation, a simple way to realize, with some reference value)

30个例程，非常好用，带有bp，GA，PSO等多种常见算法和模型，别看小，保证是全的(30 routines, very easy to use, with bp, GA, PSO and other common algorithms and models, do not look small, guaranteed to be full of)

trapezoidal rule for integration

说明：  smote算法，用于扩充对数据的采样，当某类样本量较小时，做神经网络对它的类型判断错误率就会较高，所以需要调整采样，语言matlab(smote Algorithms,which used to expand the sampling of data)

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)

基于高斯混合分布的假设，利用EM算法对数据进行分类(classification based on the Gaussian Mixtrue Models using EM algorithms)

Easy to edit weighted least squares algorithm implemented on a 3 bus test transmission network. Includes both bus and branch data. This can be also implemented on any other test transmission network that s not ill-conditioned.
