For example, if A equals the identity matrix, it is easy to see that there are infinite number of solutions: I = U I U T. This is valid for every orthogonal matrix U. Why does Matlab always return the same U and V? thomas rhett bjc

Matrix Low Rank Approximation using Matlab - Stack …

WebIf you know the rank will be small (say less than 100) and your matrix is square, use eigs(A,100) to get the 100 largest eigenvalues in magnitude. The eigenvalues are solved … WebIf you have a sufficiently large matrix where this would be infeasible, you could determine the rank of the matrix numerically using a singular value decomposition (SVD) or a rank-revealing QR decomposition. If the matrix A is n by m, and its rank is equal to min ( n, m), then it is full rank.
