LCL滤波器在现代的可再生能源行业的应用十分的普遍，可以有效、经济地确保和提高从能源到电网的馈电质量。滤波器用于过滤逆变器工作产生的开关频率。在达到目标畸变水平的同时，滤波器还会节约比较可观的成本。LCL滤波器的典型特点是损失小、体积小、重量轻、电容大。(LCL filter in the application of modern renewable energy industry is very common, can be effectively and economically to ensure and improve the quality of energy to the grid feed. This filter is used to filter the inverter switching frequency. The filter will reach the target distortion level at the same time, considerable cost savings. LCL filter typically characterized by loss, small size, light weight, large capacitance.)

Gabor-function convolution masks are increasingly used in image processing and computer vision. This function simply computes the cosine and sine masks for a given width, period and orientation. The masks returned are properly normalised. It is not highly optimised - e.g. the symmetries are not used to reduce the computation. It is recommended that convolutions with these masks are done using CONVOLVE2 (available from Matlab File Exchange) to take advantage of their low rank.

Compute chebyshev excitation coefficients for a linear array

这是MATLAB课件，有很多matlab常用的命令及使用方法，适合想学matlab的人(This is the MATLAB software, there are a lot of matlab commonly used commands and how to use, suitable for people who want to learn matlab)

Fast search for Dirichlet process mixture models (This code implements the search algorithms (modulo a few minor changes) described in the Fast search for DPMMs paper at AI-Stats 2007. It should work out of the box with a reasonably recent version of matlab. Currently the code only contains the Dirichlet/Multinomial case, but the Gaussian case can be hacked in in about 5 minutes.)
