Transpose of a Matrix: First we need to understand the transpose of a matrix to understand the symmetric matrix: LetA=[aij]m×nthen transpose ofAis denoted byATorA′orAtand is defined asAT=[aji]n×m Answer and Explanation:1 Symmetric Matrices: A square matrixAis said to be symmetric ifAT...
A square matrix M is said to be invertible if its determinant is non-zero. The determinant of a square matrix is equal to the product of its eigen values.Answer and Explanation: A matrix is said to be invertible if all its eigen values are non-zero. Since a matrix is invertible iff ...
Then A2A2 is a symmetric matrix. (here ATAT denotes the transpose of a matrix A). I guess that the following is also true : Conjecture 2 : If A2n+1=AATAAT⋯AATAA2n+1=AATAAT⋯AATA then AnAn is symmetric. PS: This second conjecture has been shown to be false when AA is ...
I want to update a symmetric matrix values using Particle Swarm Optimization, I mean the final updated matrix should be kept symmertic and maintaind the zero values as it is without changing it? This is the matrix that I want to update without changing the zero values and keep it ...

I learned how to make a non-symmetric symbolic matrix thus: Q = [ q1_1, q1_2, q1_3] [ q2_1, q2_2, q2_3] [ q3_1, q3_2, q3_3] Now I want to know if there is an easy way to make this: Q = [ q1_2, q2_2, q2_3] ...

In this paper, we show that MAC can be eliminated from DHIES if the underlying symmetric-key encryption scheme is secure in the sense of IND-CCA. Further, ElGamal encryption part of DHIES without MAC is generalized to Half-Recovery (HR) schemes. Dependent-RSA encryption scheme [12] and Bl...
How to prove that a matrix is invertible?Inverse of a Matrix:Formula for getting an inverse of a matrix:A−1=1|A|×Adj(A) where adj(A) - adjoint of A |A| - is the determinant of Matrix AAnswer and Explanation: One can simply prove that a matrix has an inverse / invertible ...
