采用matlab进行数值的逼近，用神经网络实现的。 (Using matlab numerical approximation, using neural network realization.)

说明：  用matlab建立一个网络模型。希望对大家有帮助。(Using matlab to establish a network model. We hope to be helpful.)

用matlab读取.dxf文件。本站原有代码dxf2coord_20.m中对于圆弧只能读出其圆心坐标及半径，缺少圆弧起始角及终止角，并不能在应用中实际用起来。修改后可以读出圆弧的起始角和终止角(the script can offer start angle and end angle of an arc,which are unable to access in an earlier script dxf2coord_20.m 。)

通过它把信号从时间域变换到频率域，进而研究信号的频谱结构和变化规律(discrete Fourier transform)

Implementation of Discrete fourier transform 2D (to images )

说明：  基本的粒子滤波算法，所用数值模型为带控制量的非线性模型，可修改噪声类型，并可和EKF相比较(Basic particle filter algorithm for the numerical model used to control the volume with the non-linear model, can modify the type of noise can be compared and the EKF)

基于matlab车辆车牌文字识别功能(Matlab-based vehicle license plate character recognition function)

All of MATLAB toolbox links,can download them from internet.best gift for newbies!!

Low pass and High Pass filters aplied to images as sobel, prewitt, roberts, first derivative

ofdm调制信号Matlab仿真生成代码 压缩包内为.m文件可直接用matlab打开(ofdm outer)
