dem差值计算，给定基础网格高程对相应空间迭代差值获得网格高程(dem difference calculation, given the appropriate space on the basis of the grid elevation difference of iterations to get the grid elevation)

A Matlab Code for producing LFSR Full Period for an specifeid initial vector in cryptography

用C或者matlab编写基2 FFT快速算法，输入点数是2的幂次方，序列视作既包含实部也包含虚部。要求一个函数计可以做正变换，也可以做反变换。编写输入序列，先进行正反向变换，得到离散频谱，再将离散频谱加载到输入端进行验证，从输出端获取序列，和原来的序列进行比较，看看是否相等。序列可随意设为2的幂次项！(Written by C or matlab base 2 FFT fast algorithm, the input power of 2 points is the sequence includes both the real part as the imaginary part is also included. Require a meter to do is change the function, you can also do the inverse transform. The preparation of the input sequence, first the forward and reverse transformation, discrete spectrum, discrete spectrum and then loaded into the input validation, access to sequence from the output side, and the original sequences were compared to see if equal. Sequence can be arbitrarily set to a power of 2 items!)

说明：  老师布置的一个project，里面有题目和源程序，能够识别十个数字。(Teacher arranged a project, which has subject and source, can identify 10 figures.)

对图像添加盐噪，设计一滤波器滤除盐噪声； 本人初学matlab，想有机会了解到更多的源代码，馆长给我机会啊(Add salt to the image noise, design a noise filter to filter out salt my novice matlab, would like to have the opportunity to learn more of the source code, the director for giving me the opportunity ah)

说明：  wav声音文件的通过多脉冲激励编码器，长时预测合成新的声音文件(wav sound files through the multi encoder pulse excitation, long forecast synthesis of new voice)
