关于MIMO-OFDM技术在空时分信道上的源代码，符合当今通讯应用的潮流。(About MIMO-OFDM technology in the space-time channel of the source code, in line with the trend of today s communications applications.)

此为比较奇异值分解的算法，QR分解法和分而治之法，并带入了Lapack的选择控制的接口程序，方便在matlab下实用这两种不同的算法进行比较(the algorithm about the decomposition of singular value of matrix comparing the different algorithm in the lapack QR and divide and conquer (DAC))

MATLAB 很经典的案例分析，和 matlab 神经网络30个案例分析配套

语音信号处理教材中，如何训练码书，从这段程序中可以简单地看出(Speech signal processing textbooks, how to train codebook, can simply be seen from this program )

风力发电系统仿真，变速恒频，svpwm。(Wind power generation system simulation, variable speed constant frequency, SVPWM.)

rgb2lab：rgb颜色空间向lab颜色空间转换的matlab代码，对此变换要使用不求甚解的童鞋们可以直接调用~(rgb2lab：colorspace of rgb translate to colorspace of lab。Just for the beginner~)

to find the negative of image.

程序对遗传算法进行了改进，取得了较好的效果(Application of genetic algorithm was improved, and achieved good results)

说明：  matlab 程序 实现对文字的识别，对字母F做了验证(matlab program to achieve recognition of the text of the letter F made a validation)

实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像，中间部分是低频部分，外边是图像的高频部分。经过低通滤波后，图像中的高频成分被滤除掉，只留下低频成分，图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)
