说明：  创建一个复数类，定义属性：实部、虚部。定义方法：复数加法、复数减法、复数乘法、求实部，求虚部，将复数输出，判断两个复数相等。通过一个类举例验证这些方法(Create a complex number class, custom attributes: the real part, imaginary part. Definition method: complex addition, complex subtraction, multiplication, complex, realistic Department, seeking the imaginary part, the complex output, determine the two complex numbers are equal. Verified through a class example of these methods)

It s easy to get scattering of particle with Mie theory. However, is it possible to get the optical property from experiment scattering spectra? See this inversion Mie theory....

说明：  基于matlab的三维重建技术与实现，该技术可以完美重建三维图像(three-dimensional reconstruction)

内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

Bilinear Series Parameter Estimation

该程序实现多特征自适应阈值算法，两个matlab文件，一个为函数，该函数求出信号的特征量值并通过梯度下降法训练出其初始阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其自适应阈值求出来，并一起画出图来。(The program features multi-adaptive threshold algorithm, two matlab files, one for the function,the function seek out characteristics value and initial threshold value of the signal by gradient descent , the other main function, called the function file the program seek out four signals , characteristics of each road and the adaptive threshold value,then draw them together on the map.)
