ill-condition matrix 中文意思是什麼
ill-condition matrix
解釋
病態矩陣-
We analyze the assembly model and propose a mathematics model and tree - representing model of the assembly who not only has a small data size, but also can be manipulated easily. this thesis not only gives the virtual representing concept the instance representing one, but also defines the concept of assembly constraint such as coupling, being alignment, being coaxial and being equidirectional. based on such concepts, a revised newton - raphson iterative algorithm is proposed, which can deal with the singularity and ill - condition of jacobi matrix
首先分析了裝配體的模型問題，提出了裝配體的數學模型及樹形式表示的裝配體表示模型，模型具有數據量小、操作簡單的優點：文章對所涉及的約束諸如耦合、對齊、同軸、同向的裝配體位置描述概念進行了定義，引入了裝配約柬概念，從而提高了裝配設計效率；在此基礎上，文章討論了裝配約束的求解方法，提出了newton rapson迭代法的改進演算法，使得系統能更好地處理jacobi矩陣的奇異和病態的情形。 -
For electrically large problems, the condition number of impendence matrix is very large, and furthermore, the ununiformity of the modeling leads to an ill - conditioned matrix
對大型電磁散射問題，不僅矩陣的條件數大，而且由於表面網格剖分的不均勻有可能產生病態的矩陣。 -
Then, in the light of the characteristic, based on the tikhonov regularization theorem, two new regularizers are designed to mitigate the ill - condition of the normal matrix in gps rapid positioning
基於tikhonov正則化原理，針對這種特性，設計了兩種正則化矩陣r的構造方法。通過新的正則化矩陣的作用，減弱了法矩陣的病態性。
