对图象进行预处理并进行Hough变换,然后求图象特征向量值(Preprocessing of image and Hough transform, image characteristics and then seek to Money)

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

微型逆变器初始化，简单易学，大家互相分享源码。(Micro-inverter initialization, easy to learn, we share with one another source.)

电动汽车上应用较多的永磁同步电机为基础，建立不同坐标系下永磁同步电机数学模型，并结合模型介绍矢量控制原理，根据理论分析设计了一套逆变器算法，利用Matlab/simulink软件建立永磁同步电机以转矩为目标的矢量控制仿真模型，进行系统仿真。通过仿真结果验证了该设计算法的正确性与可行性。

雷达信号处理杂波分布仿真matlab代码，包含瑞利杂波，韦伯杂波等(radar signal process)

奇异值分解用于英文文本检索，画出频率矩阵第一奇异值向量和第二奇异值向量的分布图( a fast retrieval algorithm for English texts is proposed. First of all, the English texts are mapped into frequency matrixes of order 26 and the dimensions of texts representation space are reduced through Singular Value Decomposition. Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. )
