多重网格算法实现图像的去噪，效果较好，基于rof模型，大家一起学习交流！(Multiple grid algorithm of image denoising, the effect is good, based on rof model, study with you exchange )

The system is about simple Vector Control of Permanent Magnet Synchronous Motor. The speed controller is using PI controller and the current controller is using Hysteresis band.

k-d 搜索，可以搜索大量二维数据点的距离，(k-d tree)

一维大地电磁正则化反演。matlab的程序，用的是occam算法。(One dimensional magnetotelluric regularized inversion. Matlab program, using the Occam algorithm.)

阻尼震动.用matlab编写.需要的下载(vibration damping. Prepared using Matlab. Need to download)

附件中是国外测速雷达系统仿真的matlab程序，其中对雷达系统的仿真讲的比较透彻。(Annex is abroad matlab speed radar system simulation program, in which the radar system, a thorough comparison of the simulation stresses.)

产生固定周期数的正弦脉冲信号 使用该函数时必须预先设定如下参数：正弦波的频率Fp，构成输出脉冲的正弦波的周期个数Nc，脉冲幅度A每个周期的采样点数smp。函数有两个输出：脉冲波形，以响亮sinpulse的形式输出，采样周期dt。(Produce a fixed number of cycles of the sine pulse signal         Use this function must be pre-set the following parameters: a sine wave of frequency Fp, constituting the output of the pulse cycle of the sine wave of the number Nc, the sampling points for each cycle of the pulse amplitude A smp. The function has two outputs: output pulse waveform, the a loud sinpulse form, the sampling period dt.)
