Involutry matrix

WebAn involutory matrix is a special type of matrix in mathematics. For a matrix to be involutory, it needs to be an invertible matrix, i.e., a non-singular square matrix whose inverse … WebThe singular values σ > 1 of an n × n involutory matrix A appear in pairs (σ, 1σ{1 \over \sigma }). Their left and right singular vectors are closely connected. The case of singular values σ = 1 is discussed in detail. These singular values may appear in pairs (1,1) with closely connected left and right singular vectors or by themselves.
