基于焊接图片的pca降维，knn分类算法。(Pca-based solder image dimension reduction, knn classification algorithm.)

This book is for people who want to solve ordinary differential equations (ODEs), both initial value problems (IVPs) and boundary value problems (BVPs) as well as delay differential equations (DDEs). Solving ODEs withMATLAB is a text for a one-semester course for upper-level undergraduates and beginning graduate students in engineering, science, and mathematics. Prerequisites are a first course in the theory of ODEs and a survey course in numerical analysis. Implicit in these prerequisites is some programming experience, preferably in Matlab, and some elementary matrix theory. Solving ODEs withMATLAB is also a reference for professionals in engineering, science, and mathematics. With it they can quickly obtain an understanding of the issues and see example problems solved in detail. They can use the programs supplied with the book as templates.

本程序基于matlab编写，利用最小二乘法来拟合圆形。(Matlab based on the preparation of this procedure, using the least square method to fit round.)

说明：  这些程序都是经过本人和许许多多工作过学习过的老师同学，以及一些志同道合的哥么们长期使用验证确实好使的(these procedures are numerous and I worked and studied the teachers and fellow students, and some like-minded Columbia Mody have long-term use of the test so that really)
