三维曲线曲面比较演示系统程序设计 设计一个图形用户界面（GUI）演示常见的三维函数图形，至少包含“三维绘图” 、“选项” 、“退出”等菜单，三维绘图的包括：参数方程x=e-t/20cos(t), y= e-t/20sin(t),z=t其中t 为0到2π、参数方程x=t,y=t2,z=t3其中t为0到1之间（在同一图形界面中分别绘制它们的三维曲面和三维曲线图）。“选项”菜单主要包括：网格开关，图例开关，坐标边框开关，色度空间选择菜单，曲线颜色菜单。(Comparison of three-dimensional curves and surfaces demonstration system design to design a graphical user interface (GUI) presentation function common three-dimensional graphics, at least three-dimensional graphics, options , Exit menu, etc., three-dimensional graphics, including: parameters of equation x = et/20cos (t), y = et/20sin (t), z = t one of t from 0 to 2π, parametric equation x = t, y = t2, z = t3 which t is between 0-1 (in the same graphical interface, respectively, three-dimensional mapping of their surface and three-dimensional curves). Options menu includes: grid switches, legend switches, coordinate frame switch, color space selection menu, menu color curve.)

排队论，对策论的一些源码，可以运用此源码解决一些问题哦！(Queuing theory, game theory and some of the source, this source can be used to solve some problems Oh!)

matlab的偏最小二乘分析源码，可以稍微修改下参数就可用啦(matlab partial least squares analysis of source code can be slightly modified parameters you can use)

功率谱估计 信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Power spectrum estimation signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signal are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. Is the sampling frequency. Levinson recursive method were used and Burg method for power spectrum estimation, and change the length of the data analysis, the impact on the estimation model order spectrum.)
