基于OPENCV的圆和椭圆检测程序,挺有用的。实验结果-OPENCV the circle and ellipse-based testing program, winter ridge used.

岭回归文章附MATLAB源代码，相对完整，是一篇学生论文。-Ridge Regression article attached to MATLAB source code, relatively complete, is a student paper.

多元非线性回归——岭回归方法，比常规的最小二乘更适合数据量较大的优化问题-Multiple nonlinear regression- ridge regression method is more suitable than the conventional least squares optimization problem of the large amount of data
