Least - squares solution for the inverse problem of real matrices with a submatrix constraint 子陣約束下實矩陣反問題的最小二乘解
The generalized inverse of partitioned matrices and the expression of generalized inverse using maximal nonsingular submatrix are discussed 摘要討論了分塊矩陣的廣義逆,以及用矩陣的滿秩子塊表示廣義逆。
The matrix extension problem is , under some constrained conditions , constructing a matrix a with a given matrix a as its submatrix 矩陣擴充問題就是給定矩陣a的一個子矩陣a _ 0 ,在某種約束條件下構(gòu)造矩陣a的問題。
From special to normal , the problem of constructing a jacobi matrix with a prescribed principle submatrix and two ordered defective eigen - pairs has been solved gradually in this paper 遵循從特殊到一般的原則,本文逐步解決了由給定一個順序主子陣和兩個有序缺損特征對構(gòu)造jacobi矩陣的問題。
The relationship between the rank of partitioned matrix and the one of submatrix is given with the partitioned matrix of the generalized inverse matrix , and the range of the rank of three matrices sum is obtained 摘要用分塊矩陣的廣義逆矩陣給出了分塊矩陣的秩與子塊秩的關(guān)系,及三個矩陣和的秩的范圍。
This ph . d . thesis firstly considers the jacobi matrix extension problems constrained by defective eigenpairs and a submatrix , and firstly considers the construction of a jacobi matrix from its mixed - type eigenpairs 首次提出并討論了非順序主子矩陣和缺損特征對約束下的jacobi矩陣擴充問題及由混合型特征對構(gòu)造jacobi矩陣的問題。
We compose a neural network in which the input signals are the frame substructure natural frequencies and mode shapes , and output signals are the submatrix scaling factor . the levenberg - marquardt algorithms is applied to modify the weight matrices of neural network 框架子結(jié)構(gòu)在動載作用下的自振頻率和模態(tài)作為網(wǎng)絡(luò)的輸入,子矩陣參與系數(shù)作為網(wǎng)絡(luò)的輸出,用levenberg一marquardi算法訓(xùn)練網(wǎng)絡(luò)。
On the one hand , the linear interpolation in ( x , y ) plane makes it easy to separate the three - dimensional null subspace corresponding to rigid body motions , hence what is left to do is just to compute the inverse of a symmetric definite submatrix numerically . in this way the numerical difficulty in computing general inverse can be avoided 在物理坐標系中的線性插值函數(shù)便于將三個剛體模式分離出來,從而只需計算對稱正定子陣的逆,避免了求廣義逆的數(shù)值困難;在參考坐標系中的高階插值函數(shù)則可保持原平面彈性單元的列式方式。

In mathematics, a submatrix is a matrix formed by selecting certain rows and columns from a bigger matrix. That is, as an array, it is cut down to those entries constrained by row and column.
