. Such a matrix is symmetric and so satisfies , and it has determinant . A general permutation matrix can be written as a product of elementary permutation matrices , where is such that . It is easy to show that , which means that the eigenvalues of are , where is the th root of uni...
An identity matrix is symmetric as IT = I. Every identity matrix is a scalar matrix as all its principal diagonal's elements are equal and the rest of the elements are zeros. The determinant of every identity matrix is 1. The inverse of identity matrix is itself as I · I-1 = I-1...

Diagonal Matrix Upper Triangular Matrix Lower Triangular Matrix and so on. Answer and Explanation:1 According to the given question, We have to define the column matrix. Column matrix is one of the types of matrix where the number of rows in the... ...
AES stands for Advanced Encryption Standard which is a symmetric block cipher formula with 128 bits as the block size. This means that only the sender and receiver have the key to decrypt and render the ciphertext unreadable to intruders. It allows conversion of the individual blocks using keys...
Thus, the covariance matrix is symmetric. What is the covariance matrix used for? The most common use cases of the covariance matrix are listed as follows: Mahalanobis distance: Mahalanobis distance is calculated by taking the inverse of the covariance matrix. Kalman filters: Kalman filters, or ...
LetAbe a symmetric square matrix of ordernwith real entries. Any non-singular matrixSof the same size is said to transform Ainto another symmetric matrixB = S A ST, also of order n, whereSTis the transpose ofS. 任意两个合同矩阵的惯性指数相同,即它们具有相同数目的正特征值、负特征值和零特...
