说明：  基于maltab/simulink开发的永磁同步电机的直接转矩控制（DTC）的一种方案，能快速的启动电机，各种启动参数都比较好。(Based on maltab/simulink development of permanent magnet synchronous motor direct torque control (DTC) of a program, can quickly start motor, better than a variety of startup parameters.)

详细介绍了编码原理的基础知识，是编程的入门级必备教材(Details the basics of coding theory, is an essential textbook entry-level programming)

Code for dispersion effect

multiscale log filter - finds maximum response of log filter in multiple scales and orientation, really fast(multiscale log filter- finds maximum response of log filter in multiple scales and orientation, really fast)

this is a good story book which produce good output result on matlab

均匀直线天线阵，偶极子阵，单极天线的方向图，matlab编写，输入参数可以改变(Uniform linear antenna array, dipole array, monopole antenna direction map, matlab prepared input parameters can be changed)

悬臂梁频率方程计算；将完整模型与损伤模型进行对比分析(Beam frequency equation to the full model were compared with the damage model)

有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)

电机的PWM控制：包括整流和逆变的闭环控制，MATLAB的仿真模型(PWM motor control: including closed-loop control of the rectifier and inverter, MATLAB simulation model)

一个师兄的毕设，FIR 底通和带通滤波器和IIR 底通和带通滤波器，在MATLAB中求图像纹理特征。( A complete set of brothers, Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter, In the MATLAB image texture feature.)
