In Mathematics, there are no shortcuts to understanding, but there are definitely smarter paths to scoring well.

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 ...

Set between The Matrix and The Matrix Reloaded, Kid’s Story focuses upon a teenage boy named Michael Karl Popper (voiced in the English dub by Watson) who has long sensed something being off in the ...

Abstract: A generalization of swap matrix, called a permutation matrix, is introduced in this paper. Based on permutation matrices, we further investigate the matrix expressions of symmetric games and ...

A simple check could be something like symmetric = not np.any((matrix!=matrix.T).data) (here assuming that it is scipy.sparse.csr_matrix). Here is a simple example (not the most efficient way to check ...

Abstract: In this article, a double iterative methods is suggested for solving symmetric matrix of multi-variable quadratic matrix equation. Firstly, the symmetric matrix of a quadratic matrix ...

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 ...
