WebI'm implementing a spectral clustering algorithm and I have to ensure that a matrix (laplacian) is positive semi-definite. A check if the matrix is positive definite (PD) is enough, since the "semi-" part can be seen in the eigenvalues. The matrix is pretty big (nxn where n is in the order of some thousands) so eigenanalysis is expensive. Web5 Answers. Hint: use this property: If M and N are square matrices then ( M + N) T = M T + N T (can you see why?) Now add the equations on a and b, and do something else to …
WebNov 1, 2024 · Osil's answer below seems to make more sense. We know ( A B) T = B T A T, so ( A T A) T = A T ( A T) T = A T A and hence A T A is always symmetric. Another proof per element. Let T be a transpose of A, meaning A T = T. We want to proof that R = A T is symmetric, i.e. R i, j = R j, i. Web(1e) A square matrix A is called symmetric if a ij = a ji. (1f) A square matrix A is called Hermitian if a ij =¯a ji (¯z := complex conjugate of z). (1g) E ij has a 1 in the (i,j) position and zeros in all other positions. (2) A rectangular matrix A is called nonnegative if a ij ≥0alli,j.
