三相pwm整流器

自己做用FPGA实现VGA显示时，图像提取信息的matlab程序！！！(FPGA realization of their own with VGA display, the image information extraction matlab program! ! !)

1、均值平滑、中值平滑和低通滤波平滑 2、高斯拉普拉斯算子对图像边缘的增强， 3、彩色图像的锐化，(1, the mean smoothing, median smoothing and smoothing low pass filter 2, Laplacian of Gaussian edge enhancement, 3, color image sharpening,)

相关分析过程的matlab方法，利用最小二乘算法实现对三维平面的拟合，在matlab R2009b调试通过。( Correlation analysis process matlab method, Least-squares algorithm to fit a three-dimensional plane, In matlab R2009b debugging through.)

完成对任意一个文本文件的字符统计工作。可以统计的信息有中文字符数、英文单词数、行数、字符个数（不计空格）和空格数。 (Calculate Chinese characters, English words the number of rows, number of characters (excluding spaces) and number of spaces in a txt file.)

说明：  这个是在二维下，对随机离散的点，生成二维的数据场(This is a two-dimensional, the random discrete points, generate two-dimensional data field)

说明：  应用MATLAB的M文件编程方法过行信号频域分析。分别用矩阵运算的方法计算方波的DFS，在60的时窗宽度上方波宽度分别为5与12。并且画出x(n)和DFS(x(n))的杆状图。(Application of MATLAB M-file programming off-line signal frequency domain analysis. Were calculated using matrix calculation of square wave of DFS, in the 60' s when the window width the width of the top of wave 5 and 12, respectively. And draw the x (n) and DFS (x (n)) of the rod-shaped graph.)
