When does a matrix have eigenvalues 1? When is the determinant of a matrix is zero? When is a matrix not diagonalizable? When a matrix is diagonalizable? When is the inverse of a matrix equal to its transpose? I
involutiontripotentWe give the necessary and sufficient conditions for an n × n matrix over an integral domain to be a sum of involutions and, respectively, a sum of tripotents. We determine the integral domains over which every n × n matrix is a sum of involutions and, respectively, ...
And I would like to replace the value of entire row if the row is equal to the previous row. So in this case, B = [1 2 3; 4 5 6; 1 2 3; 0 0 0] Because the last row is equal to the 3rd row of the matrix. Is there anyway I could do this?
Ybus(3,:) + Ybus(4,:) equals Ybus(5,:) so rank(Ybus) is only 4 not 5. The equation is singular and has no inverse. 댓글 수: 0 댓글을 달려면 로그인하십시오. ANNOUNCEMENT Registration Now Open for MathWorks AUTOMOTIVE CONFEREN...
When a general matrix is transformed into a companion matrix, a column vector x can be randomly generated to determine whether the generated T matrix is singular or not. If it is not, the random column vector should be regenerated. () 相关知识点: 试题来源: 解析 错误 反馈 收藏 ...
Can I perform logical indexing when the logical indexing matrix is smaller then the indexed matrix in MATLAB 7.0 (R14)?This is an error in the documentation for the LOGICAL function in MATLAB 7.0 (R14). The documentation should read as follows:

A matrix is a rectangular array in which elements are arranged in rows and columns. The pseudo-inverse of a matrix is equal to its inverse if both the columns and the rows of the matrix are linearly independent.Answer and Explanation: ...
However, after the panoramic camera video output cable is connected to the DVI matrix, the panoramic camera image can be displayed through the DVI matrix. That is, the signal does not pass through the TE80. It is suspected that the DVI matrix purchased by the customer is incompatible with ...
So far, the purpose of each nested comprehension is pretty intuitive. However, there are other situations, such as flattening lists, where the logic arguably makes your code more confusing. Take this example, which uses a nested list comprehension to flatten a matrix:Python ...
