高斯列主元消元法 测试通过 采用新算法 很好的性能(Gaussian elimination pivot column element method for testing the new algorithm through the use of good performance)

NMF在对Iris数据集上进行将为处理。(NMF:dimension reduction in the dataset Iris)

说明：  高斯坐标正反算数学模型 对于初学者来说很实用(Positive and negative Gaussian coordinate calculation model is useful)

program for signal synthetic

这是简单的一个可以绘制直线的matlab程序。这个程序只能绘制直线，圆等。程序简单，希望大家互相学习探讨。(this is a program about how to draw the line,the circle and so on.I hope we can learn the programe each other. thank you.)

混合整体最小二乘迭代法的matlab实现，供大家一块学习(he total least squares iterative hybrid method of Matlab implementation, for everyone to learn a piece)

用MATLAB编写的CP-SCFDE通信信号处理，运行方法见readme，希望能对大家有所帮助。(Using MATLAB CP-SC FDE communication signal processing, method of operation, see readme, I hope you can help.)

说明：  升压转换器是一种DC / DC电源转换器，可将电压从其输入（源）升至其输出（负载）。在连续导通模式下（流经电感的电流永远不会降为零），升压转换器的理论传递函数为： 占空比在哪里0.5 在此示例中，转换器从250 V电源馈送RC负载，并且PWM频率设置为31 kHz。 模拟 运行仿真并观察示波器上的波形。确认负载电压（Vout）的平均值非常接近理论值：Vout = 250 /（1- 0.5）= 500V。(A boost converter is a DC/DC power converter which steps up voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is: where is the duty cycle.0.5 In this example, the converter is feeding an RC load from a 250 V source and the PWM frequency is set to 31 kHz. Simulation Run the simulation and observe waveforms on Scope. Verify that the mean value of the load voltage (Vout) is very close to the theoretical value of: Vout = 250 / (1 - 0.5) = 500 V.)

说明：  希尔伯特黄变换，亲测有效，可放心使用，只是三维图运行会卡顿（三维图部分不确定正确）(Hilbert Huang transform, effective in pro test, can be used at ease, but the operation of 3D map will be stuck (the part of 3D map is uncertain))
