Elementary row Operation 等同于Elementary Matrix相乘 矩阵的逆的计算方法:A为多个Elementary Matrix的乘积
The goal is to make Matrix A have 1s on the diagonal and 0s elsewhere (an Identity Matrix) ... and the right hand side comes along for the ride, with every operation being done on it as well.But we can only do these "Elementary Row Operations":...
This lesson describes elementary matrix operations and shows how to use elementary matrix operators to perform row and column operations.
Starting with the identity matrix I and then performing exactly one elementary row operation, the resulting matrix is called an elementary matrix. Type I Elementary Matrices Let E1 be the matrix obtained by interchanging the i-th and the j-th rows of I. E1 = E1−1 E1 is symmetric. E1...
An elementary row operation, in the context of computer science, refers to a specific manipulation performed on an integer matrix. It can involve interchanging two rows, multiplying a row by a nonzero integer constant, or adding an integer multiple of a row to another row. These operations ar...

Because we can think about the three different types of elementary matrix for row operation.First,multiplying row operation--E=E(transpose).Second,interchanging row operation--E=E(transpose). Third,adding a multiple of a row operation--if E is to add n*ith row to jth row,then E(transpose...
