WebSuppose A, D, C, and B are n × n, n × m, m × n -, and m × m matrices, respectively. Then. det ( A 0 C B) = det ( A D 0 B) = det ( A) det ( B). This can be seen from the Leibniz … Web1. Yes, eigenvalues only exist for square matrices. For matrices with other dimensions you can solve similar problems, but by using methods such as singular value decomposition (SVD). 2. No, you can find eigenvalues for any square matrix. The det != 0 does only apply for the A-λI matrix, if you want to find eigenvectors != the 0-vector.
WebThe determinant is said to be a symmetric determinant when it remains the same even after taking its transpose. It is used in algebra, similar to the square matrix.

The determinant of an antisymmetric matrix depends on the dimension of the matrix. This is due to the properties of the determinants: So if the antisymmetric matrix is of odd order, its determinant will be equal to 0. But if the antisymmetric matrix is of even dimension, the determinant can take any value. flanagan smash repairs
