In the least squares method for simultaneous adjustment of several parameters, the coefficients of the normal equations are the elements of a symmetric positive-definite matrix. In order to solve the ...
Discovering faster algorithms for matrix multiplication remains a key pursuit in computer science and numerical linear algebra. Since the pioneering contributions of Strassen and Winograd in the late ...

Abstract: In this paper, we consider the problem of non-orthogonal joint diagonalization of a set of complex symmetric matrices. This appears in many signal processing problems, especially in source ...
Abstract: A new algorithm for parallel joint diagonalization of symmetric (Hermitian) matrices is introduced. The approach is based on the Jacobi diagonalization, utilizes the distribution of the ...
I'm working on a MCMC estimation algorithm by using "RcppArmadillo", but got the error message "warning: chol(): given matrix is not symmetric" and the algorithm ...
