If the transpose of a square matrix with real numbers or elements equals the inverse matrix, the matrix is said to be orthogonal. To determine whether a given matrix is orthogonal, first determine its transpose. Then, using the transpose, multiply the provided matrix. The provided matrix is or...

The inverse of a permutation matrix P is its transpose and it is also a permutation matrix and • The product of two permutation matrices is a permutation matrix. 2.4.4 Hessenberg (Almost Triangular) Matrix A square matrix A is upper Hessenberg if aij = 0 for i > j + 1. The transpos...
It is not even possible to overwrite, e.g., a non-square matrix with its transpose, even if you were willing to sacrifice the row pointers, and even if the number of matrix elements obviously stays the same. All MatObj Dia_... functions require square matrices (ht = len), whereas ...
void Transpose(); ~Matrix() { Destroy(); } /// Sets matrix to a specified size (zero is OK as long as both r and c are /// zero). The value of the new data depends on resize_type: /// -if kSetZero, the new data will be zero ...
A real matrix (one whose elements are real) is termed orthogonal if its transpose is equal to its inverse. Thus, if S is orthogonal, we may write (2.49)S−1=ST, or SST=1 (S orthogonal). Since, for S orthogonal, det(SST) = det(S)det(ST) = [det(S)]2 = ...

At each position in the row, we multiply the element times its minor times its position sign, and add all sums for the whole row. The position signs in a matrix are plus or minus depending on the position of element. For instance, the position signs in $3\times 3$ matrix are $$\...
Note also that because aTb is a 1 × 1 matrix, it is synonymous with its transpose, which is bTa. The matrix notation preserves the symmetry of the dot product. As in Section 1.7, the square of the magnitude of the vector corresponding to a will be aTa. If the elements of our ...
