21位水仙花数的寻找，里面用到了大数乘法等细节上的东西。(find the 21 digits narcissus.)

实现扫雷功能,基于c语言实现的，能够控制输入矩阵的大小(Implement demining capabilities, based on the c language, able to control the size of the input matrix)

读入红细胞图片，通过中值滤波，开运算算，闭运算，和贴标签等方法获得细胞个数 (Read into the red blood cell picture, opening operation count median filtering, and closing operation, and the labeling methods such as cell number)

说明：  fluent中作液体蒸发相变的udf，非常专业，证明可行(fluent in the evaporation of liquid phase transition for udf, very professional, proved to be feasible)

无迹卡尔曼滤波算法的c语言。网上找到的，貌似是老外编的，蛮不错的。(unscented kalman filter code of visual c.)

其基本思想是取B样条函数 为及基函数，在[a,b]中均匀划分区间，xi=a+ih,h=(b-a)/n,由于三次样条函数空间是n+3维的，所以把分点扩充到x-1,xn+1,则任意三次样条函数可用 线性组合来表示：(The basic idea is to take B-spline function and basis functions in [a, b] in the evenly divided intervals, xi = a+ ih, h = (ba)/n, because the cubic spline function is n+3 dimensional space , so the expansion points to the x-1, xn+1, then any cubic spline function can be expressed as a linear combination:)

用一个N点复序列的FFT同时计算两个N点实序列离散傅里叶变换(With an N-point complex sequence of N-point FFT calculate two real sequences discrete Fourier transform)

算术编码是用符号的概率和它的编码间隔两俩个基本参数来描述的。算术编码可以是静态的或是自适应的。(Arithmetic coding to both of two basic parameters to describe the probability of the symbol and its coding interval. Arithmetic coding can be static or adaptive.)

用来画多输入多输出系统的格式带，输入是矩阵形式(draw gershgorin)
