Constructor Detail

DenseMatrix

public DenseMatrix(int sizeOfRows,
                   int sizeOfColumns)

Constructs a dense matrix with an explicit size. All the elements are initialized to zero.

DenseMatrix

public DenseMatrix(int sizeOfRows,
                   int sizeOfColumns,
                   int capacityOfRows,
                   int capacityOfColumns)

Constructs a dense matrix with an explicit size and capacity. All the elements are initialized to zero.

DenseMatrix

public DenseMatrix(double[][] array)

Constructs a dense matrix with the same number of rows as 'array'. The number of columns will match the longest row in 'array'. Some elements can be missing from 'array' either because a row is null or too short. These elements will be set to zero in the matrix.

DenseMatrix

public DenseMatrix(double[][] array,
                   double epsilon)

Constructs a dense matrix with the same number of rows as 'array'. The number of columns will match the longest row in 'array'. Some elements can be missing from 'array' either because a row is null or too short. These elements will be set to zero in the matrix.

DenseMatrix

public DenseMatrix(MatrixI matrix)

Constructs a dense matrix with the same number of rows and columns as 'matrix'. If 'matrix' is sparse, the null elements will be set to zero in the new matrix.

DenseMatrix

public DenseMatrix(VectorI vector)

Constructs a square dense matrix with the 'vector' as the diagonal and zeros. If 'vector' is sparse, the null elements will be set to zero in the diagonal.
