ibgwww.colorado.edu= 3+ 6 − 5 = 4 Orthogonal Matrices: Only square matrices may be orthogonal matrices, although not all square matrices are orthogonal matrices. An orthogonal matrix satisfied the equation AAt = I Thus, the inverse of an orthogonal matrix is simply the transpose of that matrix. Orthogonal matrices are very important in factor analysis.
Singular Value Decomposition (matrix factorization)
courses.physics.illinois.eduRecall that columns of 1are all linear independent (orthogonal matrices), then from diagonalization (5=67612), we get: •The columns of 1are the eigenvectors of the matrix !!/ How can we compute an SVD of a matrix A ? 1. Evaluate the /eigenvectors 8 3 and eigenvalues 9 3 of !/! 2. Make a matrix 2from the normalized vectors 8 3. The columns are ...
