Cloudcompare & PCL point cloud SVD decomposition

One 、 brief introduction

SVD（ Singular value decomposition ） It is a widely used algorithm in the field of machine learning , There are many application neighborhoods , Such as the solution of rotation matrix （ICP Algorithm implementation (MATLAB Improved version )）、 Dimension reduction and simplification of data 、 Information recommendation system and naturallanguageprocessing , It is the basis of many machine learning algorithms . For more details, please refer to the article ： Singular value decomposition （SVD） as well as The application of matrix decomposition in Collaborative Filtering Recommendation Algorithm .
