basis vector中文什么意思
例句與用法
- Coordinate basis vector
坐標(biāo)基向量 - Expanding the system ' s hamiltonian to a real symmetric matrix in an appropriate orthogonal basis vector and then diagonalizing it , we get the energy spectrum of the system and calculate the energy level spacing distribution function and the spectral rigidity . then we study the statistical character of the energy spectrum under the changing of magnetic field intension and find that the system ' s motion transfers from regular to chaos gradually
將系統(tǒng)的哈密頓量在一個(gè)適當(dāng)?shù)恼换赶抡归_(kāi)并對(duì)角化，得到系統(tǒng)的能譜，分別計(jì)算系統(tǒng)能譜的能級(jí)間距分布函數(shù)和譜剛度，研究了該系統(tǒng)量子能譜的統(tǒng)計(jì)特征隨磁感應(yīng)強(qiáng)度大小的改變而表現(xiàn)出的系統(tǒng)運(yùn)動(dòng)由規(guī)則到混沌的漸進(jìn)變化。 - ( 3 ) the re - orthonormalization technique is used to solve the loss of orthonormality of basis vector during the classical gmres method solving large - scale three dimensional elasto - static be problems . based on the characteristic of fundamental solution and the coefficient matrix , several precondition methods are studied . by using the technique of re - orthonoramalization and precondition , the practical gmres method is developed based on the classical one
( 3 )采用重正交技術(shù)解決了經(jīng)典gmres方法在求解大型三維彈性靜力邊界元問(wèn)題過(guò)程中出現(xiàn)的基向量正交性喪失的問(wèn)題；結(jié)合邊界元基本解和系數(shù)矩陣的特點(diǎn)以及并行化的要求，研究了幾種預(yù)條件技術(shù)；并以重正交技術(shù)和預(yù)條件技術(shù)實(shí)現(xiàn)了經(jīng)典gmres的實(shí)用化。 - Different from other rank reduction methods , such as pca ( principal component analysis ) and vq ( vector quantization ) , nmf ( nonnegative matrix factorization ) can get nonnegative , sparse basis vectors which make possible of the concept of a parts - based representation
與pca (主分量分析)和vq (矢量量化)等降維算法不同, nmf (非負(fù)矩陣分解)算法能夠分解出非負(fù)的,稀疏的特征矩陣和編碼矩陣,能夠提取原始數(shù)據(jù)向量的局部特征,使基于局部特征進(jìn)行分類的聚類算法更容易實(shí)現(xiàn)。
