SpletManipulation of Matrices. This section is devoted to basic manipulation with matrices. For a given \( m \times n \) matrix A, its transpose is the \( n \times m \) matrix, denoted either by \( {\bf A}^T \) or by A t or just by \( {\bf A}' , \) whose entries are formed by interchanging the rows with the columns; that is, \( \left( {\bf A}' \right)_{i,j} = \left( {\bf A}' \right)_{j,i} . SpletOne way to calculate the SVD is to first calculate VTand Sby diagonalizing XTX: (5.3) and then to calculate Uas follows: (5.4) where the (r+1),...,ncolumns of Vfor which sk = 0 are ignored in the matrix multiplication of Equation 5.4.
