Method Detail

checkIdentity

public static org.ejml.data.DenseMatrix64F checkIdentity(org.ejml.data.DenseMatrix64F A,
                                                         int numRows,
                                                         int numCols)

checkZeros

public static org.ejml.data.DenseMatrix64F checkZeros(org.ejml.data.DenseMatrix64F A,
                                                      int numRows,
                                                      int numCols)

checkZerosLT

public static org.ejml.data.DenseMatrix64F checkZerosLT(org.ejml.data.DenseMatrix64F A,
                                                        int numRows,
                                                        int numCols)

Creates a zeros matrix only if A does not already exist. If it does exist it will fill the lower triangular portion with zeros.

checkZerosUT

public static org.ejml.data.DenseMatrix64F checkZerosUT(org.ejml.data.DenseMatrix64F A,
                                                        int numRows,
                                                        int numCols)

Creates a zeros matrix only if A does not already exist. If it does exist it will fill the upper triangular portion with zeros.
