WebSep 17, 2024 · Identify the diagonal of each matrix, and state whether each matrix is diagonal, upper triangular, lower triangular, or none of the above. Solution We first compute the transpose of each matrix. AT = [1 0 0 2 4 0 3 5 6] BT = [3 0 0 0 7 0 0 0 − 1] CT = [1 0 0 0 2 4 0 0 3 5 6 0] Note that IT 4 = I4. Matrix inversion is the process of finding the matrix B that satisfies the prior equation for a given invertible matrix A. A square matrix that is not invertible is called singular or degenerate. A square matrix with entries in a field is singular if and only if its determinant is zero. See more In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate), if there exists an n-by-n square matrix B such that where In denotes … See more An example with rank of n-1 to be a non-invertible matrix We can easily see … See more Suppose that the invertible matrix A depends on a parameter t.
