实现1到1000位的大数运算（包括加减乘除和浮点数运算），运行环境是vs2005(1-1000, large number operations (addition, subtraction and floating-point), the operating environment is vs2005)

说明：  利用该方程组求解一般的线性方程组，别且符合数学求解原理(Using the equations of linear equations in general, do not and in accordance with principles of mathematics to solve)

在VS2005环境下，使用CUDA编程实现SAR成像中CSA算法的实现，得到了很好的加速比。(In the VS2005 environment, using the CUDA programming SAR imaging algorithm implementation in the CSA, has been very good speedup.)

非线性方程数值解法的数学基础，有牛顿法，割线法等(Mathematical foundations of numerical solution of nonlinear equations, Newton method, secant method)

求人体信号的一个周期序列的CZT和FFT计算结果比较。是很好的程序，可以直观的看到效果。(Order to signal a cycle of the human sequence comparison CZT and FFT calculations. Is a very good program, you can see the visual effect. The body s signals.)

c语言程序编写在经验模态分解，包含三次样条(c language programming in the empirical mode decomposition, contains the cubic spline)

该文件是用matlab开发的图论分析工具箱， 里面有使用时的详细说明，pdf说明文档。 绝对实用对于图论的研究者(The document was developed with matlab graph theory analysis toolbox, which are used when a detailed explanation, pdf documentation. Absolutely useful for researchers in graph theory)

用matlab所编的关于用传输矩阵法计算光子晶体的反射率,文件中将程序写在word文档中,并附带有在matlab下画的图,感觉很有用(using Matlab as in the use of the transfer matrix method photonic crystal reflectivity, Lieutenant General procedures documents written in word document, together with the painting under Matlab plans, feeling useful)

文章简述了一位大牛研究深度学习（Deep Learning）后的心得及见解(Article outlines a large cattle study deep learning (Deep Learning) after experiences and insights)

1、根据所给的中国版图数据 绘制显示基于北京54坐标系的经纬度数据 编写兰勃特投影转换程序，转换上述数据，并显示 编写墨卡托投影转换程序，转换上述数据，并显示 同时，要绘制相对应的经纬网格，网格间距5度 2、根据所给的世界版图数据 绘制显示基于WGS84坐标系的经纬度数据 编写墨卡托投影转换程序，转换上述数据，并显示 计算北京(116.4，39.8)到巴黎(2.2, 48.52)的大圆轨迹，并显示 同时，要绘制相对应的经纬网格，网格间距5度(1, according to the Chinese territory given display data drawn based on latitude and longitude data write Beijing 54 coordinate system Lambert projection conversion process, the conversion of the data, and displays the write Mercator projection conversion process, the conversion of the data, and display the same time, Draw the corresponding latitude and longitude grid, the grid spacing of 5 degrees 2, according to the world map rendering display data written to the Mercator projection based on latitude and longitude data conversion program WGS84 coordinate system, the conversion of the data, and displays the calculation Beijing (116.4, 39.8) to Paris (2.2, 48.52) the great circle track and display the same time, to draw the corresponding latitude and longitude grid, the grid spacing of 5 degrees)
