主成分分析并用散点图分析前三个主成分M代码，请指教。(Principal component analysis and scatter analysis of the first three principal components M code, please advice.)

自己编的加噪声的 很好用哦(Own noise increases by Oh well)

牛顿拉夫逊算法进行潮流计算,希望能对大家的学习有所帮助，(Newton Raphson power flow calculation algorithm the hope that it can help everyone to learn,)

源码使用matlab将输入图像通过变换投影到球面上，主要含有coorconvert和coortransf二个m文件，实现了二维图像坐标向三维球面坐标的转换，为实现全景视频去抖提供了很大的帮助。

MU-MIMO中的快速用户配对算法的MATLAB程序。(fast user pairing algorithm in MU-MIMO)

The following Matlab project contains the source code and Matlab examples used for fitting an ellipse to a given set of points. The most accurate and robust fit minimizes geometric (orthogonal) distances the observed points to the fitting curve.
