The extension problem for rectangular matrices with values in Banach algebra to an invertible square matrix is investigated. For this problem to be solvable for a matrix D, the following condition is ...

For a symmetric correlation matrix, the Inverse Correlation Matrix table contains the inverse of the correlation matrix, as shown in Figure 40.14. The diagonal elements of the inverse correlation ...

A hyper-invertible matrix is a matrix whose every non-trivial square sub-matrix is invertible. Any m-by-n matrix induces a (linear) mapping from n input values to m output values; if the matrix is ...
