实现构建矩阵，矩阵的相加，相减，清零，以及转置，还有相乘的功能。(To build matrix, the matrix addition, subtraction, reset, and transposed, and the function of the multiplication. )

以前用VB6编写的一个计算器，支持常用的数学函数，支持弧度、角度转换，支持简单的函数作图。(A calculator writen by VB6, supports common mathematical functions, support radian, angle conversion, support simple function mapping.)

根据已知的邻接矩阵画出对应的网络图，节点用蓝点表示，连接用线表示(According to the adjacency matrix of the known draw the corresponding network diagram, the node with the blue dot, and connected with lines)

说明：  利用二阶循环统计量去除同频带干扰的影响，同时，当信号为相干信号时，也可以去相关，得到较好的结果，(Using second-order cyclic statistics to remove the influence of interference in the same frequency band)

圆面上的点到圆心的距离 圆面上的点到圆心的距离 圆面上的点到圆心的距离 圆面上的点到圆心的距离(Round surface of the distance from point to circle center point of the surface of the distance to the center circle to the center point of the surface of the distance from the surface point to the center circle distance)

本程序针对内弹道的计算实现火炮内弹道计算(The procedure for the calculation of the interior ballistics Gun Interior Ballistic calculation)

说明：  一个用C语言编写的求混沌序列的源程序,挺好的!(a C language for the chaotic sequence of the source, very good!)

用fortran语言读取NC格式的数据,与大家分享，希望能够共同进步哈，谢谢(Used fortran language to read NC data format to share with you, hoping to make progress together Ha, thank you)

说明：  MATLAB使用欧拉Euler法求解微分方程组 源程序代码(SOURCE PROGRAM CODE OF DIFFERENTIAL EQUATIONS SOURCE SOLUTION USING EULER METHOD IN MATLAB)
