在数字图像处理中，运用MATLAB中的函数entropy可以计算图像的熵或灰度出现的概率(The probability of occurrence in digital image processing, the use the MATLAB functions entropy can calculate the entropy of the image or grayscale)

matlab实现商标文字分割~第一部分计算列梯度差，计算每个像素的列方向一定范围内（n）最大值和最小值的差距,统计该差值超过某一设定域值T的像素的个数，并将该统计个数存在 GY 向量。，第二部分计算行梯度差，计算每个像素的行方向一定范围内（n）最大值和最小值的差距，统计该差值超过某一设定域值T的像素的个数，并存在 GX 向量(matlab text segmentation ~ realize trademarks calculations are shown in the first part of the gradient difference, calculated for each pixel column direction of a certain range (n) the difference between maximum and minimum values, statistics of the difference exceeds a certain threshold T set of pixels of a few, and the statistics of the number of vectors exist GY. , The second part of the calculation line gradient difference, calculated for each pixel within a certain range direction (n) the difference between maximum and minimum values, statistics of the difference exceeds a certain threshold T set the number of pixels, and the existence of GX Vector)

BCH编译码程序，对误码性能仿真，获得实际的误码曲线。(BCH Codec error performance simulation, the actual error curve.)

用scilab（和matlab一样，只是非常小）实现希尔密码的加密与解密(With scilab (and matlab, only very small) the achievement of Hill of encryption and decryption)

用声卡采集的模拟信号作为输入,然后fft变换,并且图形化的显示出来(sound card collection with the analog signal input, and then fft transform, and the graphics displayed)

MATLAB函数库查询辞典,方便查询各种函数(MATLAB function queries dictionary, easy access various functions)
