interpolation_and_fit

很好很强大,是关于双极性基带数据信号对载波进行角度调制产生BPSK信号的，有用的就下取用(strong，just for student who need it.)

对于原始图像中只含有较少的高频噪声，采用合适的小波分解洗漱阈值量化方法进行去噪(For the original image only contains less high frequency noise, the use of appropriate wash wavelet thresholding denoising method)

Digital signal processing is the important aspect of modern communication system. here is the matlab code given which helps for the beginers for understanding the basics of DSP.

一种基于稀疏变量的欠定盲分离算法，很好用，大家试一下。(Underdetermined blind separation algorithm based on sparse variables)

说明：  模拟光的折射，通过经典光学拟合光路的传输(Simulation of light refraction, through fitting the classical optical transmission of optical)

it is a function for powerflow for electrical engineering in power system.
