用matlab编写的三维FDTD计算源代码，简洁清楚(three-dimension code of FDTD)

EIGSHOW presents a graphical experiment showing the effect on the the unit circle of the mapping induced by various 2-by-2 matrices.

说明：  信道编码用于计算信道的容量，计算起来比较简单迅速。(Channel coding is used to calculate the channel capacity, calculate simple fast.)

光子晶体的算法，一个关于光子晶体的比较有用的算法，还算可以用(The algorithm of the photonic crystal, a photonic crystal, the more useful algorithms, OK)

产生随机共振现象的输入输出信噪比曲线，参数可以修改，不过过不要乱改动哦，不然振动不起来了。，已通过测试。 (SNR curve of the input and output of a stochastic resonance phenomenon, the parameters can be modified, too do not make changes Oh, or the vibration is not up. , Has been tested.)

GSCALE Scales the intensity of the input image. G = GSCALE(F, full8 ) scales the intensities of F to the full 8-bit intensity range [0, 255]. This is the default if there is only one input argument. G = GSCALE(F, full16 ) scales the intensities of F to the full 16-bit intensity range [0, 65535]. G = GSCALE(F, minmax , LOW, HIGH) scales the intensities of F to the range [LOW, HIGH]. These values must be provided, and they must be in the range [0, 1], independently of the class of the input. GSCALE performs any necessary scaling. If the input is of class double, and its values are not in the range [0, 1], then GSCALE scales it to this range before processing. The class of the output is the same as the class of the input.

LDPC码的经典的译码程序：BP译码算法(Classic LDPC code decoding procedure: BP decoding algorithm)

一个具体数据的仿真，利用matlab实现，很好的例子啊(Simulation of a specific data using Matlab achieve a good example.)

scatter plot by using matlab also fuzzy C mean

基于灰度共生矩阵提取图像纹理特征，FC为生成的特征向量(This is a method to extract features from an image by GLCM)
