LU decomposition is one technique used to factorize these entities. The Hermitian example of these objects consists of complex conjugates. The characteristic polynomial of these objects has solutions equal to eigenvalues, and their lower left corner is filled with zeros during Gaussian elimination, which converts them to their row echelon form. A system of linear equations can be solved by finding the determinants of these and applying Cramer's rule. Multiplication of two of these objects is defined only when the number of columns in the first matches the number of rows in the second. For 10 points, name these rectangular arrays of numbers or expressions.
