这是多电平svpwm空间电压矢量控制的算法，用于电机控制(This is a multi-level voltage svpwm space vector control algorithm for motor control)

正弦光栅和一个其他范例代码，大家可以根据这些进行改写，修改自己的参数(Sinusoidal grating and other examples of code, you can rewrite these, modify their own parameters)

该程序用Matlab实现hilbert-huang变换，含EMD，HHT，边际谱等，有一些实例，较完善。(The program uses Matlab to achieve hilbert-huang transform, including EMD, HHT, the marginal spectra, there are some instances better.)

详细解说了基于噪声自适应模糊选择滤波器的椒盐噪声抑制处理的原理和主要公式(Detailed explanation of the adaptive fuzzy selection filter based on noise and salt and pepper noise suppression processing principles and the main formula)

An exmaple of the JEI letter paper:texture features based on local Fourier histogram: self-compensation against rotation(JEI letter)

计算潮汐调和常数，潮汐预测,潮流的预测，能够绘制各种预测图与原始图，两者可以进行比对从而得出观测站数据的结论(Computation of tidal harmonic constants, tidal predictions, tidal current predictions, the ability to plot various prediction maps and original maps, and the two can be compared to derive observation station data.)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

The code gives us the ability to determine the optimal threshold from the gray level image.

this file is a imaging medical simulation to make quickly at your research on that field!enjoy
