One of the fundamental operations in machine learning is computing the inverse of a square matrix. But not all matrices have an inverse. The most common way to check if a matrix has an inverse or not ...

For high data rate wireless communications they use Orthogonal Frequency Division Multiplexing (OFDM) due to its high spectral efficiency and low computational complexity. It gives the architecture of ...

In this paper we study particular linear and weakly linear systems of matrix equations over semirings, with the aim of describing and computing functions as solutions to those systems. Our special ...
