Product of two psd matrices
WebbPositive Definite and Positive Semidefinite Matrices. Positive definite (PD) and positive semidefinite (PSD) matrices are very useful and appear everywhere in TCS. WebbAlthough ionosphere-free (IF) combination is usually employed in long-range precise positioning, in order to employ the knowledge of the spatiotemporal ionospheric delays variations and avoid the difficulty in choosing the IF combinations in case of triple-frequency data processing, using uncombined observations with proper ionospheric …

Webb18 juni 2015 · Dear all, I have many 2-by-2 matrices (which are covariance matrices). I want to invert them all. I'm curious if there's an efficient way of doing this. I thought, maybe, you create a cell, in which each element is one of these matrices, and then use cellfun() in some way to do it.
